Chain Abstraction

A UX design philosophy and infrastructure layer that hides blockchain-specific complexity from end users, allowing them to interact with dApps without knowing which chain they are on. Chain abstraction aggregates cross-chain routing, gas payments, bridging, and account management into a seamless experience. Projects like Particle Network and NEAR's chain signatures enable users to operate across multiple chains through a single interface.

Mental model

Mental model

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.

Technical context

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

AMMs, routing, liquidity, lending, and trading infrastructure.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

Intents

A transaction paradigm where users declare their desired outcome (e.g., 'swap 100 USDC for best SOL price') rather than specifying exact execution steps. Solvers compete to find the optimal execution path across protocols, chains, and liquidity sources. Intent-based architectures abstract away routing complexity, enable cross-chain execution, and shift MEV from adversarial extraction to competitive fulfillment.

Interoperability

The ability of different blockchains to communicate and share data or assets. Achieved through bridges (Wormhole), messaging protocols (LayerZero, Axelar), and shared standards. Cross-chain interoperability enables multi-chain DeFi, unified liquidity, and chain-agnostic applications. Solana connects to other chains primarily through Wormhole and Circle's CCTP.

Open term
Branch

Bridge (Cross-Chain)

A protocol that enables transferring assets or data between different blockchains. Bridges use mechanisms like lock-and-mint (lock on source, mint wrapped on destination), liquidity pools, or relay networks. Bridges are high-value attack targets—Wormhole ($320M, 2022), Ronin ($625M, 2022). Wormhole is Solana's primary bridge to Ethereum and other chains.

Circulating Supply

The number of tokens currently available and tradeable in the open market, excluding locked, vesting, or otherwise restricted tokens. Circulating supply is used to calculate market capitalization (price times circulating supply). It increases as vesting schedules unlock tokens and decreases as tokens are burned. The gap between circulating and max supply indicates future dilution potential.

DeFicctp

CCTP (Cross-Chain Transfer Protocol)

Circle's Cross-Chain Transfer Protocol that enables native USDC transfers between blockchains by burning USDC on the source chain and minting an equivalent amount on the destination chain. Unlike bridges that use wrapped tokens, CCTP transfers are native USDC on each chain, eliminating bridge risk and fragmented liquidity. CCTP supports Solana, Ethereum, and other major chains.

DeFicross-margin

Cross Margin

A margin mode where the entire account balance serves as collateral across all open positions. Unrealized profits from one position can offset losses in another, reducing overall liquidation risk. Cross margin is more capital-efficient but means a single bad position can threaten the entire account. Drift Protocol on Solana uses cross-margin by default for its perpetuals and spot margin trading.

Open term
DeFimev-supply-chain

MEV Supply Chain

The multi-party pipeline through which maximal extractable value is captured: searchers identify profitable orderings, builders construct optimal blocks from bundles, relays facilitate trustless builder-proposer communication, and proposers select and finalize blocks. Over 90% of Ethereum L1 blocks flow through MEV-Boost. Proposer-builder separation (PBS) aims to formalize these roles at the protocol level.

DeFi

AMM (Automated Market Maker)

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.

Open term
DeFi

CLMM (Concentrated Liquidity Market Maker)

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.

Open term
DeFi

Liquidity Pool

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.

Open term
DeFi

LP Token

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.
