WalletManagerEvm

Defined in: wallet-evm/src/manager.ts:19

One seed → EVM accounts at m/44’/60’/0’/0/i (BIP-44; MetaMask / ethers default). The 64-byte BIP-39 seed is held for the life of the manager and zeroized on dispose().

Built with a secp256k1 Signer instead of a seed, the manager wraps it:

• a derivable SeedSigner sitting at m/44'/60'/0'/0 yields getAccount(i) children;
• a SeedSigner at a leaf, or any external signer, is getAccount(0) (path = the signer’s path, or ‘external’); other indexes/paths throw.

Extends

• WalletManager<WalletAccountEvm, EvmConfig>

Constructors

Constructor

new WalletManagerEvm(seedOrSigner, config?): WalletManagerEvm

Defined in: wallet-evm/src/manager.ts:20

Parameters

seedOrSigner

string | Uint8Array<ArrayBufferLike> | Signer

config?

EvmConfig = {}

Returns

WalletManagerEvm

Overrides

WalletManager<WalletAccountEvm, EvmConfig>.constructor

Methods

cachedAccount()

protected cachedAccount(key, create): Promise<WalletAccountEvm>

Defined in: core/dist/index.d.ts:295

The account cached under key, built by create at most once: concurrent calls share one build. Throws once the manager is disposed; an account whose build finishes after dispose() is disposed itself and the call throws, so no live signing account outlives the manager.

Parameters

key

string

create

() => WalletAccountEvm | Promise<WalletAccountEvm>

Returns

Promise<WalletAccountEvm>

Inherited from

WalletManager.cachedAccount

---

dispose()

dispose(): void

Defined in: core/dist/index.d.ts:302

Dispose every derived account and zeroize the seed; subclasses zeroize their own extras first, then call super.

Returns

void

Inherited from

WalletManager.dispose

---

externalSigner()

protected externalSigner(): Signer | undefined

Defined in: core/dist/index.d.ts:281

The Signer this manager was built with, if any (no mnemonic then). Chain managers decide how to turn it into accounts.

Returns

Signer | undefined

Inherited from

WalletManager.externalSigner

---

getAccount()

getAccount(index?): Promise<WalletAccountEvm>

Defined in: wallet-evm/src/manager.ts:25

Account index on the chain’s standard path. Cached per index.

Parameters

index?

number = 0

Returns

Promise<WalletAccountEvm>

Overrides

WalletManager.getAccount

---

getAccountByPath()

getAccountByPath(path): Promise<WalletAccountEvm>

Defined in: wallet-evm/src/manager.ts:29

Account at an explicit path. Cached per path.

Parameters

path

string

Returns

Promise<WalletAccountEvm>

Overrides

WalletManager.getAccountByPath

---

getFeeRates()

getFeeRates(): Promise<FeeRates>

Defined in: wallet-evm/src/manager.ts:61

normal = feeRate × 1.0, fast = × 1.2, slow = × 0.8.

Returns

Promise<FeeRates>

Overrides

WalletManager.getFeeRates

---

getReadOnlyAccount()

getReadOnlyAccount(address): WalletAccountReadOnlyEvm

Defined in: wallet-evm/src/manager.ts:56

Watch-only account for any address, sharing this manager’s provider config.

Parameters

address

string

Returns

WalletAccountReadOnlyEvm

---

requireSigner()

protected requireSigner(curve): Signer

Defined in: core/dist/index.d.ts:283

The external signer, asserted to sign on curve; throws when the manager holds a mnemonic instead.

Parameters

curve

SignerCurve

Returns

Signer

Inherited from

WalletManager.requireSigner

---

seedBytes()

protected seedBytes(): Uint8Array

Defined in: core/dist/index.d.ts:275

The 64-byte seed this manager derives from; throws for a Signer-built or disposed manager.

Returns

Uint8Array

Inherited from

WalletManager.seedBytes

---

signerAccount()

protected signerAccount(key, signer, relativePath, build): Promise<WalletAccountEvm>

Defined in: core/dist/index.d.ts:300

cachedAccount over an injected signer: the signer itself (relativePath undefined) or its child along relativePath. A child that never becomes an account is disposed.

Parameters

key

string

signer

Signer

relativePath

string | undefined

build

(leaf, publicKey) => WalletAccountEvm

Returns

Promise<WalletAccountEvm>

Inherited from

WalletManager.signerAccount
