HIP-1341: Bringing Ethereum's Pectra Upgrade to Hedera

HIP-1341 brings the execution-layer features of Ethereum's Pectra upgrade to the Hedera Smart Contract Service, live on Hedera Mainnet since Release 77 in September 2026. Smart contracts on Hedera now run on the Prague EVM, with native BLS12-381 cryptography, Ethereum-aligned calldata pricing, and full gas accounting for access lists. Most contracts keep working unchanged, but developers who hardcode gas limits for data-heavy transactions or deploy very large contracts are directed to an Action Required section.
