# SDK Cases

This page lists the route cases currently covered by the operations testcase matrix in [web/packages/operations/src/testcases/testAll.ts](https://github.com/Snowfork/snowbridge/blob/main/web/packages/operations/src/testcases/testAll.ts).

## Ethereum -> Polkadot

Examples covered:

* `ethereum:1 -> polkadot:1000` with `DOT`
* `ethereum:1 -> polkadot:2000` with `ETH`
* `ethereum:1 -> polkadot:2004` with `WETH`
* `ethereum:1 -> polkadot:2030` with `ETH`
* `ethereum:1 -> polkadot:2034` with `USDC`
* `ethereum:1 -> polkadot:2043` with `TRAC`
* `ethereum:1 -> polkadot:3369` with `MYTH`

## Polkadot -> Ethereum

Examples covered:

* `polkadot:1000 -> ethereum:1` with `DOT`
* `polkadot:2000 -> ethereum:1` with `ETH`
* `polkadot:2004 -> ethereum:1` with `WETH`
* `polkadot:2030 -> ethereum:1` with `ETH`
* `polkadot:2034 -> ethereum:1` with `USDC`
* `polkadot:2043 -> ethereum:1` with `TRAC`
* `polkadot:3369 -> ethereum:1` with `MYTH`
* `ethereum:1284 -> ethereum:1` with `WETH`

## L2 -> Polkadot

Examples covered:

* `ethereum_l2:10 -> polkadot:1000` with `ETH`
* `ethereum_l2:42161 -> polkadot:1000` with `WETH`
* `ethereum_l2:8453 -> polkadot:1000` with `USDC`

## Polkadot -> L2

Examples covered:

* `polkadot:1000 -> ethereum_l2:10` with `ETH`
* `polkadot:1000 -> ethereum_l2:42161` with `WETH`
* `polkadot:1000 -> ethereum_l2:8453` with `USDC`

## Inter-Parachain

Examples covered:

* `polkadot:1000 -> polkadot:2034` with `USDC`
* `polkadot:2034 -> polkadot:1000` with `USDC`

## Registration

Examples covered:

* Agent creation with `api.createAgent()`
* Token registration with `api.registerToken()`

## Common SDK Pattern

Most route cases follow the same pattern:

```typescript
const sender = api.sender(from, to)
const transfer = await sender.build(
    sourceAccount,
    beneficiaryAccount,
    tokenAddress,
    amount,
    options,
)
```

The returned `transfer.tx` can then be submitted to the wallet by your application.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.snowbridge.network/developers/snowbridge-v2/typescript-sdk/cases.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
