# DeFi Core Suite

From the first mainnet block, X1 EcoChain ships a full “foundational stack” so builders are never stuck waiting for wallets or liquidity rails:

<mark style="color:green;">**ecoDEX bridge**</mark> – a permissionless cross-chain bridge that connects X1 EcoChain to the major EVM and non-EVM networks. It is secured by the PoN validator set and uses wrapped assets, so value can move in and out without trusted custodians

<mark style="color:green;">**Token Constructor**</mark> – a no-code interface that mints an ECO-20 token, pre-configures vesting schedules and liquidity locks. Ten minutes and you have a live token with a market

<mark style="color:green;">**Open SDK & Indexer**</mark> – JavaScript, Python, and Rust libraries plus a GraphQL event indexer. If you can build on Ethereum, you can build here with almost no code changes

Together these tools mean you can design a token, bootstrap its liquidity, bridge outside capital, and list it — all before lunch.
