API Reference

window.ethereum.request()​

All interactions go through the standard EIP-1193 request method:

window.ethereum.request({ method: string, params?: unknown[] }): Promise<unknown>

Methods​

eth_requestAccounts​

Opens Temple wallet via Beacon and returns the EVM alias for the connected tz1 address.

const accounts = await window.ethereum.request({ method: 'eth_requestAccounts' });
// → ['0x341af4de1e67241d8d2536b2ea47c7e9debf7cb2']

eth_accounts​

Returns the currently connected account without prompting.

const accounts = await window.ethereum.request({ method: 'eth_accounts' });
// → ['0x341af4de...'] or []

eth_chainId / net_version​

Chain ID as hex (eth_chainId) or decimal string (net_version).

await window.ethereum.request({ method: 'eth_chainId' });    // → '0x1f440'
await window.ethereum.request({ method: 'net_version' });    // → '128064'

eth_getBalance​

Returns the balance of an address in wei (as hex). Proxied to Tezlink.

await window.ethereum.request({
  method: 'eth_getBalance',
  params: ['0x341af4de...', 'latest']
});

eth_getTransactionCount​

Returns the current nonce for an address. Proxied to Tezlink.

await window.ethereum.request({
  method: 'eth_getTransactionCount',
  params: ['0x341af4de...', 'latest']
});

eth_call​

Read-only call against an EVM contract. Proxied to Tezlink.

await window.ethereum.request({
  method: 'eth_call',
  params: [{ to: '0x...', data: '0x2e64cec1' }, 'latest']
});

eth_sendTransaction​

Routes a transaction through the NAC gateway. Opens Temple for signature and returns a synthetic hash (the real kernel-synthesized hash is resolved lazily — see EIP-1193 → synthetic hash).

const syntheticHash = await window.ethereum.request({
  method: 'eth_sendTransaction',
  params: [{
    to: '0x...',
    data: '0xd09de08a',          // e.g. increment() selector
    value: '0x0',
  }]
});

eth_getTransactionByHash​

Resolves the real kernel-synthesized EVM transaction when called with a synthetic hash returned by eth_sendTransaction. Falls back to a Tezlink proxy for any other hash.

await window.ethereum.request({
  method: 'eth_getTransactionByHash',
  params: [syntheticHash]
});
// → { hash: '0xrealHash', from, to, blockNumber, ... }

eth_getTransactionReceipt​

Resolves the real receipt (with real logs, gasUsed, blockNumber) by scanning EVM blocks from the send-time snapshot onward. Returns a synthetic receipt after timeout if nothing matches.

await window.ethereum.request({
  method: 'eth_getTransactionReceipt',
  params: [syntheticHash]
});

wallet_revokePermissions / wallet_disconnect​

Disconnects the Temple session and clears all pending op mappings.

await window.ethereum.request({ method: 'wallet_revokePermissions' });

Fee model methods (short-circuited)​

Tezos X fees are paid on the Michelson runtime via the NAC gateway, not on the EVM runtime. Proxying EVM fee calls to the Tezlink node therefore returns values that cannot be coalesced into a coherent fee model by client libraries (ethers.js v6 throws could not coalesce error when it tries to assemble these for BrowserProvider.populate).

To keep EVM clients happy during transaction population, the relayer short-circuits these methods to fixed, well-formed constants:

MethodReturnsRationale
eth_estimateGas0x1e8480 (2 000 000 gas)Conservative upper bound. Actual fees are paid in tez on L1 — the gas figure is cosmetic.
eth_gasPrice0x0No EVM-side gas price — fees come from the L1 operation.
eth_maxPriorityFeePerGas0x0EIP-1559 priority fee is not applicable.
eth_feeHistory{ oldestBlock: '0x0', baseFeePerGas: ['0x0'], gasUsedRatio: [0], reward: [['0x0']] }Minimal valid envelope.

RPC proxy (fallback)​

Any JSON-RPC method not listed above (and not in the fee-model table) is forwarded transparently to the Tezlink EVM node. This unblocks ethers.js tx.wait(), viem, wagmi and any other library that relies on methods like eth_blockNumber, eth_getBlockByNumber, eth_getCode, eth_getLogs, etc.

await window.ethereum.request({ method: 'eth_blockNumber' });
await window.ethereum.request({
  method: 'eth_getLogs',
  params: [{ address: '0x...', fromBlock: '0x0', toBlock: 'latest' }]
});

Events​

window.ethereum.on('accountsChanged', (accounts) => { /* ... */ });
window.ethereum.on('chainChanged',    (chainId)  => { /* ... */ });
window.ethereum.on('connect',         (info)     => { /* { chainId } */ });
window.ethereum.on('disconnect',      (err)      => { /* EIP-1193 error */ });
