paris EVM target. - Precompile & Interop Guidance: Documents all precompile contracts (staking, governance, IBC, bank, address conversion, pointer, Wasm) with Solidity interfaces for EVM-CosmWasm interoperability. - Deployment & Troubleshooting: Includes deployment walkthroughs, contract verification on Seitrace, error-code references, and fixes for common issues like PUSH0 opcode failures. - Use Case: Deploy an ERC20 token to Sei mainnet with Foundry, then query a CW20 token's ERC20 pointer contract and read associated Cosmos-native balances from an EVM address. ## Quick Start Ask the agent to deploy a Solidity contract to Sei testnet using Foundry with the correct chain configuration.High-intent search queries and answers about installing and using this skill.
Set evm_version = "paris" in foundry.toml, then run forge create with --rpc-url https://evm-rpc.sei-apis.com and your private key. Mainnet chain ID is 1329 and testnet (atlantic-2) is 1328.
Sei's EVM targets the paris hard fork and does not support the PUSH0 opcode introduced in Shanghai. Set evmVersion to "paris" in your Foundry or Hardhat compiler config, then clean and recompile.
Precompiles are built-in contracts at fixed addresses (0x...1001 through 0x...100b) exposing Cosmos-native functions like staking, governance, IBC transfers, and address conversion. Call them from Solidity using CALL only; DELEGATECALL is not supported for state-changing operations.
A pointer contract is a lightweight proxy that makes a CW20 token accessible as an ERC20 (or vice versa) without wrapping or bridging. Query the Pointer precompile at 0x...100b with getPointer to find or verify a registered pointer address.
Yes, Sei EVM is bytecode-compatible with Ethereum, so Hardhat, Foundry, viem, and ethers.js work without custom plugins. The only required change is setting the EVM version to paris and using Sei's chain IDs and RPC endpoints.
SEI uses 18 decimals in the EVM (wei) but 6 decimals in the Cosmos bank module (usei). The chain converts automatically across precompiles and pointer contracts, but IBC transfer amounts follow the Cosmos 6-decimal convention.
