The eth_blobBaseFee JSON-RPC endpoint is now exposed on Sei but returns a JSON-RPC error (code -32000, "blobs not supported on this chain") since Sei does not support EIP-4844 blob transactions.
Skill gap addressed
The change is purely an RPC-behavior/documentation nuance: eth_blobBaseFee moved from returning -32601 (method not found) to -32000 (blobs not supported). No skill file documents eth_blobBaseFee explicitly, so a targeted update to the two files that discuss EIP-4844/blob support is appropriate rather than creating a new skill. The rpc-providers.md and rpc-agent-skills.md files list supported RPC methods generically and do not enumerate eth_blobBaseFee, so they don't strictly require changes. Note the diff's RPC_IO_README/FAILED_TEST_ANALYSIS still show the old -32601 message in some rows, which is a source-repo inconsistency and not something to propagate to skill files.
Files changed
skill/references/evm/overview.md— The blob opcodes / EIP-4844 section states blobs are 'Not supported', but does not mention that eth_blobBaseFee is now exposed and returns JSON-RPC error -32000 ('blobs not supported on this chain') rather than -32601 method-not-found. Update the blob-related notes to reflect the new behavior.skill/references/migration/from-ethereum.md— Section 5 ('No EIP-4844 Blobs') describes BLOBBASEFEE as unavailable; clarify that the eth_blobBaseFee JSON-RPC endpoint is now exposed but deliberately returns error -32000 ('blobs not supported on this chain'), so migrating apps should not expect a fee value.Generated by sei-docs-bridge.
