Methods

formSendTx

formSendTx(options: {
    amount: number;
    denom: string;
    fee: number;
    gasPrice: number;
}): {
    amount: Coin[];
    fee: StdFee;
}
Prepares transaction data by calculating the amount and fee. Returns the amount and fee in the format required by the SigningStargateClient.sign method.

Property
The amount of tokens to send.

Property
The denomination of the tokens to send.

Property
The gas price to use for the transaction.

Property
The fee to use for the transaction.

Returns
An object containing the amount and fee in the format required by the SigningStargateClient.sign method.
Parameters
- options: {
      amount: number;
      denom: string;
      fee: number;
      gasPrice: number;
  }
  
  Transaction configuration.

  - denom: string
  - fee: number
  - gasPrice: number
Returns {
amount: Coin[];
fee: StdFee;
}
- amount: Coin[]
- fee: StdFee

getAccounts

getAccounts(): Promise<readonly AccountData[]>
Returns account data, including the algorithm used, the address, and the compressed public key

Returns Promise<readonly AccountData[]>
Implementation of OfflineDirectSigner.getAccounts
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:108

getAddress

getAddress(): Promise<string>
Return address

Returns
- Cosmos address
Returns Promise<string>
Inherited from PKPBase.getAddress
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:101

getClient

getClient(): Promise<SigningStargateClient>
getClient is an asynchronous function that creates and returns a SigningStargateClient instance. The SigningStargateClient is connected to the provided rpcEndpoint, and the wallet instance itself acts as the signer.

Returns
A promise that resolves to a SigningStargateClient instance connected to the rpcEndpoint with the wallet as the signer.

Returns Promise<SigningStargateClient>
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:195

getRpc

getRpc(): any
Returns any
Implementation of PKPClientHelpers.getRpc
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:72

handleRequest

handleRequest(payload: any): Promise<any>
Parameters
- payload: any
Returns Promise<any>
Implementation of PKPClientHelpers.handleRequest
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:80

setRpc

setRpc(rpc: string): Promise<void>
Parameters
- rpc: string
Returns Promise<void>
Implementation of PKPClientHelpers.setRpc
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:76

sign

sign(messages: readonly EncodeObject[], fee: StdFee, memo: string, explicitSignerData?: SignerData): Promise<{
    authInfoBytes: Uint8Array;
    bodyBytes: Uint8Array;
    signatures: readonly Uint8Array[];
}>
*** NOTE: This is a copy of the SigningStargateClient.sign method ***

Gets account number and sequence from the API, creates a sign doc, creates a single signature and assembles the signed transaction.

The sign mode (SIGN_MODE_DIRECT or SIGN_MODE_LEGACY_AMINO_JSON) is determined by this client's signer.

You can pass signer data (account number, sequence and chain ID) explicitly instead of querying them from the chain. This is needed when signing for a multisig account, but it also allows for offline signing (See the SigningStargateClient.offline constructor).

Returns
A promise that resolves to an object containing the signed transaction bytes and signature array
Parameters
- messages: readonly EncodeObject[]
  
  An array of messages to be signed, following the EncodeObject format
- fee: StdFee
  
  The transaction fee object, containing the gas limit and amount
- memo: string
  
  An optional memo string to be included in the transaction
- Optional explicitSignerData: SignerData
  
  Optional SignerData to be used during signing (e.g., account number, sequence, and chain ID)
Returns Promise<{
    authInfoBytes: Uint8Array;
    bodyBytes: Uint8Array;
    signatures: readonly Uint8Array[];
}>
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:263

signDirect

signDirect(address: string, signDoc: SignDoc): Promise<DirectSignResponse>
Signs the provided transaction using the LIT node client and returns the signed transaction and the encoded signature.

Returns
A promise that resolves to a DirectSignResponse containing the signed transaction and the encoded signature.
Parameters
- address: string
  
  The address of the signer.
- signDoc: SignDoc
  
  The transaction data to be signed.
Returns Promise<DirectSignResponse>
Implementation of OfflineDirectSigner.signDirect
- Defined in packages/pkp-cosmos/src/lib/pkp-cosmos.ts:127
