Methods

parse(psbtObject) → {Object}

Parameters:
Name Type Description
psbtObject Object

the PSBT
Overrides:
Source:
Returns:

signatures - This calls a function in unchained-bitcoin which parses PSBT files for sigantures and then returns an object with the format { pubkey1 : [sig1, sig2, ...], pubkey2 : [sig1, sig2, ...] } This format may change in the future or there may be additional options for return type.

Type
Object

request() → {Object}

Request for the PSBT data that needs to be signed.

NOTE: the application may be expecting the PSBT in some format other than the direct Object.

E.g. PSBT in Base64 is interaction().request().toBase64()

Overrides:
Source:
Returns:

Returns the local unsigned PSBT from transaction details

Type
Object

(async) run() → {void}

Throws an error.

Overrides:
Source:
Throws:

An error since this is an indirect interaction.

Returns:
Type
void
