brainblast v0.6.2 — 3 Solana ecosystem packs
Warning
This release has a broken installer. The SHA256SUMS file was not updated after SKILL.md changed, causing a checksum mismatch for anyone running the installer pinned to v0.6.2. Use v0.6.3 instead.
What's new in v0.6.2
Three HIGH-severity Solana ecosystem packs, all PROVEN (RED→GREEN via npm run synth with existing vetted checkers — no new logic):
solana-sendtx-unconfirmed — @solana/web3.js
connection.sendTransaction() submits a transaction and returns a signature immediately — it does not wait for the network to confirm the transaction landed. If the transaction is dropped due to congestion, validator restart, or blockhash expiry, the code continues as if it succeeded. Fix: use sendAndConfirmTransaction().
metaplex-nft-royalty-zero — @metaplex-foundation/js
metaplex.nfts().create({ sellerFeeBasisPoints: 0, … }) bakes zero royalties into the NFT's on-chain metadata at mint time. Metaplex token-metadata is immutable after mint — there is no correction path short of burning and reminting the entire collection. Fix: set sellerFeeBasisPoints to the intended value (e.g. 500 = 5%).
raydium-compute-zero-slippage — @raydium-io/raydium-sdk-v2
raydium.liquidity.computeAmountOut({ slippage: 0, … }) sets minAmountOut === amountOut with zero tolerance, meaning any price movement between compute and on-chain execution — including a sandwich attack — executes the swap at a worse rate with no revert protection. Fix: set slippage to a nonzero value (e.g. 0.5 = 0.5%).
