A Token-2022 extension that invokes a custom program on every token transfer. The hook program receives the transfer details and can enforce additional logic (royalties, compliance checks, transfer restrictions). The hook program address is set on the mint. Hooks execute via CPI and must conform to the Transfer Hook Interface.
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.
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.
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.

Firm maintaining official ownership ledger for securities, processing transfers and ensuring compliance. Securitize acts as transfer agent for BlackRock's BUIDL. Token-2022's transfer hook maps directly to programmable transfer agent logic on-chain.

The next-generation token program (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb) that extends SPL Token with configurable extensions. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, metadata, and more. Token-2022 is backwards-compatible with SPL Token for basic operations.

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.
