# Tezos / Cross-Chain Network Config and Env Matrix

Frozen config and environment variables for ChainID 138, ALL Mainnet (651940), Etherlink (42793), and Tezos L1 relay.

## Network matrix

| Network        | Chain ID | RPC env                     | CCIP selector env           | Relay / bridge envs |
|----------------|----------|-----------------------------|-----------------------------|----------------------|
| ChainID 138    | 138      | `RPC_URL_138`, `CHAIN_138_RPC_URL` | Custom / DON                | `CCIP_ROUTER_CHAIN138`, `CCIPWETH9_BRIDGE_CHAIN138`, `RELAY_ROUTER_MAINNET`, `RELAY_BRIDGE_MAINNET` |
| ALL Mainnet    | 651940   | `CHAIN_651940_RPC_URL`, `CHAIN_651940_RPC` | N/A (no CCIP)               | AlltraAdapter; AlltraCustomBridge |
| Etherlink      | 42793    | `ETHERLINK_RPC_URL`         | `ETHERLINK_CCIP_SELECTOR` (if CCIP) | `ETHERLINK_RELAY_BRIDGE`, `ETHERLINK_RELAY_PRIVATE_KEY` (if custom relay) |
| Tezos L1       | 1 (registry) | N/A (relay uses Tezos RPC) | N/A                         | `TEZOS_RPC_URL`, `TEZOS_RELAY_ORACLE_KEY` |

## RPC URLs (defaults)

| Network     | Default RPC |
|-------------|-------------|
| ChainID 138 | `https://rpc-http-pub.d-bis.org` |
| ALL Mainnet | `https://mainnet-rpc.alltra.global` |
| Etherlink   | `https://node.mainnet.etherlink.com` |
| Tezos (relay) | TzKT / Tezos RPC (e.g. `https://api.tzkt.io` or mainnet RPC) |

**Tezos explorer (contracts list):** [https://tzkt.io/contracts](https://tzkt.io/contracts) — use to verify Tezos token and contract addresses (FA1.2/FA2, KT1).

## CCIP / selector

| Network     | Selector / notes |
|-------------|------------------|
| Ethereum Mainnet (destination) | `5009297550715157269` |
| ChainID 138 (source) | Custom (e.g. 138) or from DON config; see [CHAIN138_SELECTOR_NOTES](../../smom-dbis-138/docs/deployment/CHAIN138_SELECTOR_NOTES.md) |
| Etherlink   | Set `ETHERLINK_CCIP_SELECTOR` only if CCIP supports 42793 |

## Shared deploy / scripts

- `PRIVATE_KEY`
- `BRIDGE_REGISTRY_ADDRESS`
- `UNIVERSAL_BRIDGE_ADDRESS`
- `CHAIN_REGISTRY_ADDRESS`

## Per-network parameters

- **Confirmations / reorg**: See [multi-chain-execution config](../../multi-chain-execution/src/chain-adapters/config.ts) (`confirmations`, `reorgWindowBlocks`).
- **Fee tokens**: LINK for CCIP; native for custom relay and Tezos relay.
