A crypto asset that aims to maintain a stable value relative to a specified asset or basket, almost always the US dollar. As of 2026, ~99% of stablecoin supply is USD-pegged. The category splits into fiat-backed, crypto-collateralised, synthetic, and bank-issued sub-types.
A stablecoin whose value is collateralised one-for-one by cash and cash-equivalent reserves held by a non-bank issuer. USDT and USDC are the canonical examples. Under the GENIUS Act and MiCA this is the only model permitted as a payment stablecoin.
A stablecoin collateralised by other crypto assets (typically over-collateralised) rather than fiat reserves. DAI and Sky's USDS are the live examples. Distinct from fiat-backed in that the backing itself is volatile and must be over-provisioned.
A stablecoin whose peg is maintained by smart-contract supply adjustments rather than collateral. Mostly extinct after TerraUSD's 2022 collapse. Regulators in both the GENIUS Act and MiCA functionally exclude pure-algorithmic designs from the payment stablecoin perimeter.
A stablecoin whose USD peg is maintained via a delta-neutral position rather than 1:1 fiat backing, typically a long spot crypto position hedged with a perpetual short. Ethena's USDe is the dominant example. Economically and legally distinct from payment stablecoins; usually classified as a synthetic asset.
The regulatory category codified by the GENIUS Act of 2025 (and equivalent under MiCA's EMT regime): a digital asset designed for payment or settlement, issued by a non-bank entity, fully reserved 1:1 with liquid assets, redeemable at par, and prohibited from paying yield to holders.
The reserve discipline required of regulated payment stablecoin issuers: every token in circulation is matched by an equivalent unit of cash or cash-equivalent reserves. Both the GENIUS Act and MiCA codify this as the floor, with monthly disclosure of reserve composition required.
The right of any stablecoin holder to redeem one token for one unit of the reference asset (typically 1 USDC for $1) at face value. Required by both the GENIUS Act and MiCA. Operationally enforced via the issuer's redemption queue, typically with same-day settlement for verified institutional accounts.
The asset mix backing a stablecoin's supply, typically a blend of cash on deposit at insured banks, short-dated US Treasury bills, and overnight repo. The composition determines liquidity under redemption stress; over-allocation to longer-dated or less-liquid assets is the failure mode that produces de-peg events.
A break in a stablecoin's market price from its nominal peg, typically on the downside. Causes range from undercollateralisation (TerraUSD 2022) to bank counterparty failure (USDC briefly to $0.87 in March 2023 on the Silicon Valley Bank weekend). De-peg severity is measured by both the depth and the duration of the gap.
The explicit prohibition on payment stablecoin issuers paying interest or yield to holders, codified by the GENIUS Act and MiCA. The rule preserves the deposit-versus-stablecoin distinction and protects bank deposit franchises. Bank-issued tokenized deposits are not subject to it.
Mandatory monthly public disclosure of a regulated stablecoin issuer's reserve composition, attested by an independent accounting firm. Required by both the GENIUS Act and MiCA. Distinct from a full audit (annual) but the operational discipline that underpins issuer transparency.
The regulatory authorisation required to issue a payment stablecoin. Under the GENIUS Act this is a new US federal license modeled on state money transmitter law. Under MiCA, EMT issuers need an EMI license; ART issuers need authorisation under MiCA's bespoke regime. Bank-issued deposit tokens fall under existing banking licenses.
The self-reinforcing dynamic by which dominant stablecoins (USDT, USDC) attract more liquidity, listings, and integrations than smaller competitors, making them progressively harder to dislodge. Among the reasons the top five stablecoins now control ~90% of supply.
A blockchain-native representation of a bank deposit liability, issued by a licensed bank against its balance sheet. JPMorgan's JPMD on Base is the canonical example. Economically identical to a regular bank deposit, including yield permission and FDIC eligibility, but settled on a public or permissioned chain.
The issuance of a blockchain-native digital token that represents ownership of, or a claim on, an off-chain asset, a deposit, a money market fund, a Treasury bill, a commodity, real estate. The mechanism by which traditional financial assets enter on-chain settlement systems.
A traditional financial asset (Treasury bill, money market fund share, commercial paper, real estate) issued or wrapped as a blockchain token. Distinct from stablecoins in that the underlying is yield-bearing and the token represents fractional ownership rather than a redemption claim on cash reserves.
A money market fund whose shares are issued as blockchain tokens, allowing 24/7 transfer and use as on-chain collateral while preserving the underlying fund's regulated structure. BlackRock's BUIDL and Franklin Templeton's BENJI are the largest. As of 2026 the total tokenized-MMF market sits around $15B with concentration in four major funds.
A US Treasury bill or note issued or wrapped as a blockchain token, settling on-chain rather than through traditional clearing infrastructure. Ondo's OUSG, BUIDL's underlying, and the upcoming DTCC tokenized Treasuries (October 2026) are the principal forms. The fastest-growing real-world-asset category in 2025–2026.
Delivery-versus-payment settlement in which the asset transfer and the cash transfer happen simultaneously on a shared ledger, with each conditional on the other. The gold standard for securities settlement; rarely achieved across crypto + fiat rails today because the asset and cash legs typically sit on different ledgers.
The traditional financial-services function of holding assets on behalf of clients, applied to the off-chain assets that back tokenized products. For a tokenized money market fund, custody happens off-chain at a regulated custodian; the on-chain token represents a claim on those custodied assets.
A protocol that enables an asset issued on one blockchain to be represented and used on another, typically by locking the original token and minting a synthetic representation on the destination chain. Bridges are historically the single largest source of crypto losses through smart-contract exploits.
Circle's native USDC cross-chain transfer protocol. Instead of locking USDC on one chain and minting a synthetic wrapper on another, CCTP burns USDC on the source chain and mints native USDC on the destination, eliminating bridge-style synthetic-wrapper risk for the dominant US stablecoin.
Chainlink's generic cross-chain messaging and value-transfer protocol. Used by tokenized-asset issuers, banks, and exchanges to move tokens and instructions across heterogeneous chains with a unified security model. The most institutionally-adopted cross-chain standard as of 2026.
The Guiding and Establishing National Innovation for U.S. Stablecoins Act, signed into law on 18 July 2025. The first U.S. federal regulatory framework for payment stablecoins. Defines payment stablecoins as 1:1-reserved non-bank-issued tokens, mandates monthly attestation, prohibits yield to holders, and explicitly excludes bank deposit obligations from the definition.
The EU's Markets in Crypto-Assets regulation, in force since June 2024. Splits stablecoins into two regulatory categories: e-money tokens (EMTs) backed by a single fiat currency, and asset-referenced tokens (ARTs) backed by a basket. Both regimes prohibit yield to holders. The first comprehensive crypto-asset regulation in a major jurisdiction.
Under MiCA, a crypto asset that aims to maintain stable value by referencing multiple fiat currencies, commodities, or crypto assets. Subject to MiCA's most stringent prudential regime, significant ART issuers face capital, governance, and conflict-of-interest requirements similar to a credit institution.
Under MiCA, a crypto asset that aims to maintain stable value by referencing the value of one official currency (typically EUR or USD). Functionally the EU's payment stablecoin category. Must be issued by a credit institution or an authorised electronic money institution. EURC and EURI are early EMT examples.
The New York Department of Financial Services limited-purpose trust company charter, used by Paxos (USDP), Gemini (GUSD), and several other US-regulated stablecoin issuers. Operationally rigorous: monthly attestation, full segregation of customer reserves, NYDFS approval required for new tokens or new chains.
The Monetary Authority of Singapore's regulatory framework for SGD- or G10-currency stablecoins issued in Singapore. Requires 100% reserve backing, prudential capital, redemption within five business days. The first major Asia-Pacific stablecoin regime; XSGD and emerging Singapore-based USD stablecoins fall under it.
The FDIC's Notice of Proposed Rulemaking, opened December 2025, clarifying that tokenized representations of insured deposits remain eligible for FDIC coverage at the issuing bank's existing limit. The regulatory codification that made JPMD's launch on Base operationally credible.
The requirement that financial institutions transmit originator and beneficiary information alongside transactions above a regulatory threshold ($3,000 in the US, €1,000 in the EU). Extended to virtual asset service providers in 2019 by FATF. The single most consequential AML rule for stablecoin and crypto-payment infrastructure.
The customer-identification and due-diligence process financial institutions perform on every new account holder. For stablecoin issuers and tokenized-asset platforms KYC happens at the issuance and redemption boundary; on-chain transfers themselves are not KYC-ed in most jurisdictions, only on/off-ramp transactions.
The body of regulation requiring financial institutions to detect and report suspicious transactions, maintain records, and screen against sanctions lists. For stablecoin operators AML obligations apply at the issuer's mint/burn perimeter and at any regulated venue that handles fiat conversion.
A blockchain on which any participant can read, write, and validate transactions without permission from a central authority. Ethereum, Tron, Solana, BNB Smart Chain, the XRP Ledger, Bitcoin. Distinct from permissioned chains used by consortium banking initiatives.
A blockchain whose validators and participants are pre-approved by a governing body. Used by JPMorgan's Kinexys, Partior, Fnality, and most bank-consortium settlement systems. Trades the censorship-resistance of public chains for operational control, compliance integration, and predictable settlement guarantees.
Layer 1 is the base settlement layer of a blockchain (Ethereum mainnet, Bitcoin). Layer 2 is a scaling solution built on top of an L1 that batches transactions for cheaper, faster execution while inheriting L1 security. Base, Arbitrum, and Optimism are Ethereum L2s; JPMD's choice of Base over a private chain is the highest-profile bank deployment on an L2.
A service that brings off-chain data (asset prices, identity attestations, banking signals) onto a blockchain in a verifiable way. Chainlink is the dominant provider. Oracles are a single point of failure for many DeFi and tokenized-asset systems and a recurring source of de-peg or liquidation incidents.
A peer-to-peer trading venue built as smart contracts, where users swap tokens against on-chain liquidity pools rather than through a centralised order book. Uniswap, Curve, Pancake, Raydium. Stablecoins are the largest single asset class on DEXs by volume.
A custodial trading platform where balances and most trading activity settle off-chain on internal ledgers. Binance, Coinbase, Kraken, OKX. The largest concentration of stablecoin balances globally; most stablecoins enter a CEX once and never leave, used internally for trading and derivatives.
The Depository Trust & Clearing Corporation's tokenization service going live in October 2026. Will tokenize US Treasury bills and bonds at the centre of the US settlement perimeter. The most consequential 2026 infrastructure event for regulated digital assets, moves DTCC from observer to active participant in on-chain settlement.
A payment architecture in which value moves across multiple settlement systems (correspondent banking, card networks, stablecoin chains, instant payment rails) chosen dynamically per corridor and currency. The dominant institutional pattern for cross-border treasury and disbursement in 2026.
A digital form of central bank money, issued and backed directly by a central bank. Distinct from stablecoins (private issuer) and tokenized deposits (commercial bank issuer). As of 2026 wholesale CBDC pilots (Project Agorá, mBridge, Project Helvetia) are far more advanced than retail rollouts.
Mastercard's institutional orchestration network for tokenized money movement. Sits between on-chain asset rails and bank cash rails, coordinating cross-leg settlement. Used in the May 2026 Kinexys-Ondo-Ripple cross-border tokenized Treasury redemption pilot as the seam between XRPL and correspondent banking.
The Bank for International Settlements' wholesale tokenized commercial bank money workstream, running through 2026 with seven central banks and a roster of major commercial banks. The most active multilateral experiment in cross-border tokenized settlement using bank money rather than stablecoins.
AI systems that can plan and execute multi-step tasks autonomously, not just answer a query but take actions across tools, APIs, and workflows. In regulated finance the deploy-ready use cases are treasury reconciliation, KYC review, exposure monitoring, and contract review under human-in-the-loop oversight.
The practice of constraining a large language model's responses to a specific, trusted body of source material, through retrieval-augmented generation, citation enforcement, or fine-tuning. The mechanism that makes LLM output defensible enough for regulated use.
A pattern in which an LLM, before answering, retrieves relevant context from an external knowledge base, vector store, database, document set, and answers using that context. Reduces hallucination and enables institutional content (such as tracee's briefings and this glossary) to ground AI assistant responses with verifiable citations.
An AI workflow design in which a human reviewer approves, modifies, or rejects an AI-generated action before it is committed. The default for any agentic AI workflow in regulated finance, the regulator's preferred bridge between model output and consequential action.
The process of matching internal transaction records against bank and counterparty statements to confirm that funds, positions, and obligations are correctly recorded. One of the highest-leverage agentic AI use cases in finance, high volume, repeatable, mistake-tolerant under human review.
