provider
{ request({ method: string, params: unknown[] }): Promise<unknown> }
An EIP-1193 request function function.
ts
import { customRpc } from './rpc'
const transport = custom({
async request({ method, params }) {
const response = await customRpc.request(method, params)
return response
}
})import { customRpc } from './rpc'
const transport = custom({
async request({ method, params }) {
const response = await customRpc.request(method, params)
return response
}
})key (optional)
string
A key for the Transport. Defaults to "custom".
ts
const transport = custom(
provider,
{
key: 'windowProvider',
}
)const transport = custom(
provider,
{
key: 'windowProvider',
}
)name (optional)
string
A name for the Transport. Defaults to "Ethereum Provider".
ts
const transport = custom(
provider,
{
name: 'Window Ethereum Provider',
}
)const transport = custom(
provider,
{
name: 'Window Ethereum Provider',
}
)retryCount (optional)
number
The max number of times to retry when a request fails. Defaults to 3.
ts
const transport = custom(provider, {
retryCount: 5,
})const transport = custom(provider, {
retryCount: 5,
})retryDelay (optional)
number
The base delay (in ms) between retries. By default, the Transport will use exponential backoff (~~(1 << count) * retryDelay), which means the time between retries is not constant.
ts
const transport = custom(provider, {
retryDelay: 100,
})const transport = custom(provider, {
retryDelay: 100,
})
