Open-source contributions: Satya Kwok

Rust infrastructure engineer. Merged work across the Rust Ethereum stack (alloy, CometBFT, and Foundry), with active PRs in Reth, Lighthouse, and Agave. I also build and run Sentrix Chain, a Rust EVM Layer-1 with a live public testnet.

This is a curated index of upstream contributions. Merged engineering work is listed first; in-review PRs and Sentrix Chain ecosystem listings are kept separate.

Merged

Execution and ABI tooling: alloy / Foundry

• alloy-rs/core#1122: validate the event topic count before decoding the dyn-ABI log body. ERC-20 and ERC-721 Transfer share the same topic0, so a topic-only filter matches both; decoding an ERC-721 log against the ERC-20 ABI overran the body and surfaced a confusing Overrun instead of a clear TopicLengthMismatch.
• alloy-rs/core#1124: propagate extra_derives to the generated sol! function-calls enum, the one generated enum that silently dropped user derives like Debug/PartialEq. Root-caused to the expansion-context attributes being reset before the calls enum was expanded; one-line fix plus a regression test that fails to compile on main.
• alloy-rs/alloy#3976: saturate out-of-u64 baseFeePerGas on header deserialization instead of failing outright. Some EVM chains return values above u64::MAX (chain id 988 returns 10^21 for a range of blocks), which broke RPC deserialization entirely; fix follows the maintainer-preferred saturate-on-deser direction.
• foundry-rs/foundry-core#91: preserve base paths in generated block-explorer URLs. Url::join dropped the sub-path (e.g. /explorer) for explorers not hosted at a bare domain, producing wrong links; fixed by normalizing the base to a trailing slash.

Consensus / BFT: CometBFT

• cometbft/cometbft#5857: add LoadValidatorsFast to skip the proposer-priority advance on the replay path. Up to 903x faster validator-set loads far from a checkpoint (126 ms to 140 µs on a 100-validator set; the issue reported ~10x in production).
• cometbft/cometbft#5890: proposer self-verifies its own vote extension before broadcasting. Without it, an app whose ExtendVote emits data its own VerifyVoteExtension rejects deadlocks the chain: the issuing validator advances locally while peers loop rejecting the extension and 2/3 precommits are never reached. The guard fails fast locally with a clear message.
• cometbft/cometbft#5861: reject out-of-int-range float RPC IDs in idFromInterface. Large numeric JSON IDs above MaxInt all saturated to MinInt, silently colliding and breaking request/response correlation; the fix uses a float round-trip that also catches the 2^63 rounding boundary a naive bound check misses.

TUI: Ratatui

• ratatui/ratatui#2594: keep a large scrollbar thumb inside the track at the end position. When the content is shorter than the viewport the thumb is large relative to the track; thumb_start and thumb_length were clamped independently, so at the end thumb_start + thumb_length could exceed the track and the trailing end symbol was dropped. Fixed by clamping the thumb to the track length.

In review

Active upstream PRs in the repositories I want to work in:

• paradigmxyz/reth#25224: use the furthest-reached stage as the pipeline-consistency reference so a stale first stage cannot mask execution falling behind headers (relates to #23234).
• foundry-rs/foundry#15128: return a complete eth_feeHistory from anvil when the cache lags the chain head.
• sigp/lighthouse#9435: add Unix-domain-socket support for the beacon HTTP API.
• anza-xyz/agave#13076: surface rollback accounts in fees-only transaction simulation results.
• alloy-rs/core#1129: derive Default for dynamic arrays of non-Default elements in the sol! macro.
• alloy-rs/alloy#4040: saturate the base fee on the increase path to guard against u64 overflow.

Plus smaller in-review fixes across Ratatui, XRPL, and candle.

Sentrix Chain ecosystem listings

Merged registry and integration PRs for Sentrix Chain, the Rust EVM L1 I operate (listed separately from the engineering work above):

• wevm/viem#4603: Sentrix mainnet (7119) and testnet (7120) chain definitions.
• ethereum-lists/chains#8266: chain metadata.
• DefiLlama/chainlist#2707: chainlist entry.
• DefiLlama/icons#2374: icon assets.

Projects

• Sentrix Chain: a Rust EVM Layer-1 with a native Rust node, EVM execution via revm, BFT consensus, and full RPC / explorer / faucet / validator tooling.
• reliakit: a zero-dependency Rust reliability toolkit (no_std-friendly, no unsafe) covering retry/backoff, timeout, rate limiting, circuit breaker, bounded collections, secret redaction, and health checks.
• evm-rust-lab: practical Rust examples for Ethereum/EVM workflows with Alloy, REVM, and real RPC.
• solana-infra-doctor: Solana RPC readiness diagnostics and redaction-safe reporting in Rust.
