env-verifiers

Use env-verifiers to set transaction verifier names and capabilities. This function enables you to define a list of objects with the "name" key specifying the verifier name, and the "caps" key specifying a list of associated capabilities.

Basic syntax

To set the signature keys for transaction verifiers, use the following syntax:

(env-verifiers [verifiers])

Each verifier is an object that consists of a verifier name and a list of capabilities in the following format:

(env-verifiers [{"name":verifier_name, "caps":[capabilities]}])

For each object, the verifier_name is the verifier signature to add to scope, and caps is the list of capabilities that the verifier_name is scoped to.

Arguments

Use the following argument to set verifier information using the env-verifiers Pact function.

Argument	Type	Description
verifiers	[object]	Specifies the list verifier objects where each object represents a verifier name to add to scope and a list of associated capabilities that the verifier is scoped to.

Return value

The env-verifiers function returns a string indicating that the transaction verifiers have been set.

Examples

The following example illustrates using the env-verifiers function to grant the "COOLZK" and "HYPERCHAIN-BRIDGE" verifiers.

pact> (module accounts g (defcap g () true) (defcap USER_GUARD (user:string) true))
Loaded module accounts, hash 8aj3ezifsdCMX3l-A7p6Axbd59YJRsGR4MgDoR9qPgc
pact> (module bridge g (defcap g () true) (defcap MINT (coin:string amount:integer) true))
Loaded module bridge, hash 9r3-A9e5vYGyKXTHTQVVq58Z2AJ4vWQeTP1uCTmZdPA
pact> (env-verifiers [{'name: "COOLZK", 'caps: [(accounts.USER_GUARD "my-account")]}, {'name: "HYPERCHAIN-BRIDGE", 'caps: [(bridge.MINT "mycoin" 20)]}])
