Use the TypeScript SDK session APIs after authentication to restore wallet state, issue ID tokens, and manage credential access.

​
Session Restore

The default storage backend is browser localStorage when it is available. Non-browser runtimes use in-memory storage unless you provide a custom StorageManager. OIDC redirect state defaults to browser sessionStorage. Browser signing defaults to a non-extractable WebCrypto P-256 credential stored through IndexedDB when available, so raw private key bytes are not written to localStorage. 
import { MemoryStorageManager, OMSClient } from '@0xsequence/typescript-sdk'

const oms = new OMSClient({
  publicApiKey: 'YOUR_PROJECT_ACCESS_KEY',
  projectId: 'YOUR_PROJECT_ID',
  storage: new MemoryStorageManager(),
  redirectAuthStorage: new MemoryStorageManager(),
})

if (oms.wallet.session.walletAddress) {
  console.log('Restored wallet:', oms.wallet.session.walletAddress)
}
Returns oms.wallet.session returns OMSClientSessionState with walletAddress, expiresAt, loginType, and sessionEmail.

​
List Wallets

List wallets available to the authenticated credential. 
const wallets = await oms.wallet.listWallets()

for (const wallet of wallets) {
  console.log(wallet.id, wallet.type, wallet.address)
}
Parameters Takes no parameters. Returns Returns Promise<OmsWallet[]>.

​
Get ID Token

Request an ID token for the active wallet session. Send this token to your backend when using backend wallet verification. 
const idToken = await oms.wallet.getIdToken({
  ttlSeconds: 300,
})
Parameters
ParameterTypeDescription
ttlSecondsnumber or undefinedOptional token lifetime in seconds.
customClaimsRecord<string, unknown> or undefinedOptional custom claims to include in the token.
Returns Returns Promise<string>.

​
List Access

List credentials that currently have access to the active wallet. 
const grants = await oms.wallet.listAccess()

for (const grant of grants) {
  console.log(grant.credentialId, grant.expiresAt, grant.isCaller)
}
Parameters
ParameterTypeDescription
pageSizenumber or undefinedOptional page size used while following Wallet API cursors.
Returns Returns Promise<AccessGrant[]>.

​
List Access Pages

Use listAccessPages when your UI should render credential access one page at a time. 
for await (const page of oms.wallet.listAccessPages({ pageSize: 25 })) {
  for (const grant of page.grants) {
    console.log(grant.credentialId, grant.isCaller)
  }
}
Parameters
ParameterTypeDescription
pageSizenumber or undefinedOptional page size for each Wallet API request.
Returns Returns AsyncIterable<AccessGrantPage>.

​
Revoke Access

Revoke another credential’s access to the active wallet. 
await oms.wallet.revokeAccess({
  targetCredentialId: 'credential-id',
})
Parameters
ParameterTypeDescription
targetCredentialIdstringCredential ID returned by listAccess.
Returns Returns Promise<void>.

​
Sign Out

await oms.wallet.signOut()
Signing out clears wallet metadata from storage, pending OIDC redirect auth state, and the configured credential signer when supported. Parameters Takes no parameters. Returns Returns Promise<void>.
