Variable: hidekiTestnet

const hidekiTestnet: object

Defined in: packages/sdk/src/chains/definitions/hidekiTestnet.ts:32

Hideki testnet (chain id 50383) — the low-latency Tokyo network. Validators sit in one region to keep validator-to-validator latency low, so blocks land every 10 ms (~100 blocks/s) instead of Shannon's 100 ms. Native token is STT.

One live-verified oddity, so nobody "fixes" it: Hideki's network id is not its chain id. eth_chainId answers 0xc4cf (50383) — the value here, the one wallets and signatures use — while net_version answers 50000258 (0x2faf182). Shannon's and mainnet's two ids are equal; Hideki's are not.

The 10 ms cadence is what makes this the interesting target for latency work: a blockTime of 10 is what viem uses to size its own polling/waiting heuristics, and the SDK's live tail sees ~10x the block rate of Shannon.

Multicall3 lives at a NON-canonical address (deployed 2026-08-10 by the bridge infra, byte-identical to the canonical runtime). The canonical 0xcA11bde0… route is permanently unreachable here: Somnia chains charge ~4,928 gas per deployed byte, so the presigned "Nick's method" transaction (fixed 500k gas limit) cannot deploy Multicall3's 3,808-byte runtime, and the presigned deployers' nonce-0 transactions have already been burned on these networks. The same address holds the same bytes on Shannon — one deployer key at the same nonce on both chains — but Shannon's definition keeps its earlier deployment for parity with viem's somniaTestnet.

No public block explorer is known for Hideki, so that field stays unset.
