Precompile Version Matrix

Track precompile availability and behavioral changes across Sei chain releases.

All precompile addresses are stable. Version changes affect behavior, gas costs, or available methods—not addresses.

Precompile	Address	Available Since
Addr		v5.5.2
Bank		v5.5.2
Staking		v5.5.2
Distribution		v5.5.2
Governance		v5.5.2
Oracle		v5.5.2
IBC		v5.5.2
Pointer		v5.5.2
PointerView		v5.5.2
Solo		v6.1.4
JSON		v5.5.2
P256		v6.0.6

Behavioral Changes by Release

Version	Changes
v6.1.11	•`eth_estimateGas` now caches pointer lookups, eliminating underestimation during migrations •Transaction receipts expose accurate `gasUsed` matching Tendermint execution •Synthetic logs include `synthetic=true` flag for indexers (Bank, Distribution, Staking) •Recommended for production deployments
v6.1.4	•Solo precompile introduced at `0x100C` for asset migration •Adds `claim()` and `claimSpecific()` methods for legacy Cosmos → EVM transfers •Required for SIP-3 migration workflows
v6.0.6	•P256 precompile added at `0x1011` implementing RIP-7212 •Enables secp256r1 signature verification (~48,000 gas, 60x more efficient than Solidity) •Supports WebAuthn, passkeys, Secure Enclave, hardware wallets
v6.0.0	•Pointer system hardening for CW20/CW721/CW1155 registration •Improved version tracking and existence checks
v5.7.5	•`associatePubKey()` method added to Addr precompile •Improved signature verification for `associate()` calls
v5.5.2	•Initial precompile suite: Addr, Bank, Staking, Distribution, Governance, Oracle, IBC, Pointer, PointerView, JSON, Wasmd

⚠️

Always test against the target network version. Testnet may run newer releases than mainnet; verify via eth_chainId and RPC endpoint documentation. Pair chain releases with matching go-ethereum fork versions (e.g., v1.15.7-sei-7 for v6.1.11).
