I got my relayer to relay an IBC payment from the cosmos testnet to our devnet!

![15.00 Photon in my wallet](https://www.diigo.com/file/image/brpqocpzpbeerecapzepbqeqpq/SwingSet+Solo+REPL+Demo.jpg)

## Starting a hermes relayer between cosmos and agoric testnets

_Grab the Makefile etc. by, for example, cloning this gist. Then:_

1. `make task/restore-keys` to:
- build a docker image for the [Hermes IBC Relayer CLI](https://github.com/informalsystems/ibc-rs/tree/master/relayer-cli) (v0.9.0)
- create a docker volume for the state
- generate a mnemonic; import ("recover") secrets for accounts on both chains
2. **Update `ADDR_AG`, `ADDR_COSMOS` in `Makefile`** with the addresses from step 1.
3. `make task/tap-agoric-faucet`; follow instructions to tap the faucet; then `touch task/tap-agoric-faucet`
3. `make task/create-channel` to:
- tap cosmos faucet
- create an IBC channel
4. Take note of the channel ids (details below)
5. `make start` or `docker-compose up -d` to start the relayer.

Creating the IBC channel results in something like this that includes the channel ids:

```

```

## Provision user account on agorictest-6

Normally [Setting up an Agoric Dapp Client with docker compose](https://github.com/Agoric/agoric-sdk/wiki/Setting-up-an-Agoric-Dapp-Client-with-docker-compose) would suffice, but:

**ISSUE**: needs `home.pegasusConnections` special power due to
https://github.com/Agoric/agoric-sdk/issues/4153

I don't have good notes on how I did this... `agoric start --devnet`? Anyway... the address is

`agoric18kzgpc36eacsdhx8wrdjywvdu3s6dsg2ae3t54`

## Create peg and import issuer

Using [contract/src/deploy-peg.js](https://github.com/Agoric/agoric-sdk/blob/ibc-example-scripts/packages/pegasus/scripts/deploy-peg.js) based on `pegasus/demo.md`:

```
$ agoric deploy contract/src/deploy-peg.js
Open CapTP connection to ws://127.0.0.1:8000/private/captp...o
agoric: deploy: running /home/connolly/projects/agoric/ibc-fun/contract/src/deploy-peg.js
agoric: deploy: Deploy script will run with Node.js ESM
awaiting home...
awaiting pegasusConnections...
pegasusConnections: 11
getting instance, publicFacet
creating peg-channel-10-uphoton from /ibc-port/transfer/unordered/ics20-1/ibc-channel/channel-10
await brand, issuer, board...
{ issuerBoardId: '495234043' } {
cosmos: { keyword: 'Photon', denom: 'uphoton', decimalPlaces: 6 },
agoric: { channel: 'channel-10' }
}
```

mostly follow pegasus/demo.md (IOU details)

create purse

trick: set auto-deposit in REPL

## Set up keplr

import both chains using wallet.agoric.app

## Send payment with keplr

- start on cosmos hub testnet
- ibc transfer
- create channel to agoricdev-6 (@@src channel from above)
- payee from agoric wallet

hermes relayer logs say:

```

We can look at the transaction and see the details:

`ag-cosmos-helper --node http://139.59.8.130:26657 query tx 410AD46232C10FB7062B778F94C587238CA45B51EA8BA1A78DD47AC742EF4237` shows:

```

## Payment shows up in agoric wallet

See screenshot above.

## IBC Send using Zoe Offers
