EVMBrowserSigner

Defined in: atomiq-chain-evm/src/evm/wallet/EVMBrowserSigner.ts:10

Browser-based EVM signer, intended for injected/external wallets. This ensures no explicit signTransaction() flow is required and transaction submission goes through sendTransaction().

Constructors

Constructor

new EVMBrowserSigner(
   account, 
   address, 
   usesECDSADN?): EVMBrowserSigner;

Defined in: atomiq-chain-evm/src/evm/wallet/EVMBrowserSigner.ts:23

Parameters

Parameter	Type	Description
account	Signer	Signer account to request signatures and send transaction through
address	string	Signer address
usesECDSADN?	boolean	Optional flag indicating whether the signer supports signing using ECDSA-DN (deterministic nonce) algorithm, this allows the wallet to produce reproducible entropy. Only pass true here if you are 100% sure that the signer supports this!

Returns

EVMBrowserSigner

getReproducibleEntropyMessage()

static getReproducibleEntropyMessage(appName): string;

Defined in: atomiq-chain-evm/src/evm/wallet/EVMSigner.ts:28

Returns a static message, which should be signed by the EVM wallets to generate reproducible entropy. Works when wallets use signing with deterministic nonce, such that signature over the same message always yields the same signature (same entropy).

Parameters

Parameter	Type	Description
appName	string	Application name to differentiate reproducible entropy generated across different apps

Returns

string

sendTransaction()

sendTransaction(transaction, onBeforePublish?): Promise<TransactionResponse>;

Defined in: atomiq-chain-evm/src/evm/wallet/EVMBrowserSigner.ts:55

Signs and sends the provided EVM transaction. Maps common wallet rejection errors to a consistent user-facing message.

Parameters

Parameter	Type	Description
transaction	TransactionRequest	A transaction to sign and send
onBeforePublish?	(txId, rawTx) => Promise<void>	Optional callback called after signing and before broadcast when available

Returns

Promise<TransactionResponse>

optional signTransaction(transaction): Promise<string>;
