Compliance with US Treasury OFAC sanctions prohibiting transactions with designated individuals/entities. Circle blacklists sanctioned USDC addresses on-chain. Solana RWA protocols must screen wallets against the SDN list before whitelisting.
Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a market mechanic used to price, route, or move capital through liquidity apps.
Place the term inside its Solana layer so the definition is easier to reason about.
AMMs, routing, liquidity, lending, and trading infrastructure.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

List of wallet addresses prohibited from holding or transacting a token due to OFAC sanctions, suspicious activity, or court orders. USDC (Circle) maintains a blacklist using SPL Token's freeze_authority. Token-2022's permanent delegate enables recovery from blacklisted accounts.
List of wallet addresses that have completed KYC/AML verification and are permitted to hold a security token. Maintained by issuer or transfer agent, checked on every transfer via Token-2022 transfer hook. Required for all regulated tokenized assets.
Identity verification procedures required by financial regulations that involve confirming a user's real-world identity through government-issued documents, proof of address, and sometimes biometric checks. Centralized exchanges and fiat on-ramp services typically require KYC before allowing trading or withdrawals. Most DeFi protocols on Solana are permissionless and do not require KYC, which is both a feature (accessibility) and a regulatory concern.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

These entries live beside the current term and help the page feel like part of a larger knowledge graph instead of a dead end.
A protocol that enables token swaps using algorithmic pricing against pooled liquidity instead of matching individual buyers and sellers. AMMs use mathematical formulas (typically constant product x*y=k) to determine prices based on the ratio of tokens in a liquidity pool. On Solana, major AMMs include Raydium, Orca, and Meteora.
An AMM design where liquidity providers concentrate their capital within specific price ranges instead of across the full 0-to-infinity range. CLMMs dramatically improve capital efficiency—LPs earn more fees per dollar deposited within their active range. If the price moves outside the range, the position becomes inactive. Orca Whirlpools and Raydium CLMM are leading implementations on Solana.
A smart-contract-held reserve of two or more tokens that enables trading via an AMM. Users deposit token pairs in specified ratios to become liquidity providers and earn trading fees. Pools are identified by their token pair and fee tier. Pool depth (total value locked) determines price impact for trades.
A token issued to liquidity providers representing their proportional share of a pool's reserves and accrued fees. LP tokens can be burned to withdraw the underlying assets. The value of LP tokens changes as the pool's token ratios shift and fees accumulate. LP tokens are often stakeable in yield farming programs for additional rewards.
