What is Base chain?

Base is an Ethereum Layer-2 network incubated by Coinbase and built on the OP Stack, the same technology behind Optimism. As a Layer-2, it processes transactions off the Ethereum main chain and posts the results back to Ethereum, which gives it low fees and fast confirmations while still inheriting Ethereum’s security for final settlement.

Since its public launch in 2023 it has grown one of the larger DeFi and consumer ecosystems among L2s, helped by its Coinbase backing and direct fiat on-ramps. Being EVM-compatible, it runs standard Ethereum smart contracts unchanged, so the wallets, tooling and DEXes traders already know work the same way — just cheaper and faster. That low cost is what makes activities like frequent swapping or managing concentrated-liquidity ranges practical for ordinary users.

Sally operates natively on Base across all of its tools — swap aggregation, liquidity pools, honeypot scanning and liquidity locks. On Base, Sally routes through venues including Uniswap V2/V3/V4 and Aerodrome’s Slipstream concentrated pools, so the same best-route trading, safety checks and verifiable locks available on BNB Smart Chain apply here too, at Layer-2 fees.
