Technical specifications for how Base works at the chain level. Core Primitives covers what developers interact with directly — tokens, accounts, bridging, fees, and transactions. Network Systems covers protocol internals — the batcher, consensus, execution, and proof system.

Core Primitives

B20

Native token standard with compliance, memos, and supply controls.

Native Account Abstraction

Smart accounts that send ordinary transactions with no bundlers or relays.

Bridging

Move ETH, stablecoins, and tokens to and from Base.

Network Fees

L2 execution fees, L1 security fees, and cost-saving strategies.

Transaction Ordering

How transactions are ordered by priority fee and arrival time.

Transaction Finality

Confirmation stages from unsafe through finalized.

Flashblocks

Sub-second block building, WebSocket data, and RPC usage.

Network Systems

Protocol

Rollup architecture, core components, and user flows.

Batcher

Posting L2 sequencer data to L1 for data availability.

Standard Bridges

Cross-domain ETH and ERC-20 transfers between L1 and L2.

Consensus

L2 block derivation, P2P networking, and RPC specification.

Execution

EIP-1559 parameters, fee vaults, and Engine API behavior.

Proofs

Multi-proof checkpoint verification with TEE and ZK provers.

Throughput and Limits

Gas limits and throughput-related network parameters.
