# Deployed Contracts (Testnet)

The Gravity Longevity Testnet (L1, Chain ID `7771625`) ships the same standard EVM ecosystem contracts as mainnet, at their **universal cross-chain addresses** — the same addresses they occupy on Ethereum, Base, Arbitrum, Gravity Mainnet, and most other EVM chains. Because tooling (viem, ethers, wagmi, Foundry, wallet SDKs, ERC-4337 bundlers, Safe UI, …) hardcodes these addresses, any dapp that relies on them works on the testnet with **zero per-chain configuration**.

{% hint style="warning" %}
**Deployment in progress.** These preinstalls are deterministic, so their testnet addresses are identical to [mainnet](/developer-resources/deployed-contracts.md) and are known ahead of deployment. Rollout to the Longevity Testnet is ongoing — **verify each address has code before relying on it** (see [Verify before you hardcode](#verify-before-you-hardcode)).
{% endhint %}

{% hint style="info" %}
These are the standard, audited ecosystem deployments — distinct from Gravity's own **system runtime contracts** in the `0x1625Fxxxx` range.
{% endhint %}

## Deployer factories (L1, chain ID `7771625`)

## Safe{Wallet} smart-account suite (v1.4.1)

The canonical [Safe](https://safe.global) contract suite deploys at its universal addresses, so the Safe SDK / Transaction Service and any Safe-based tooling work on the testnet.

| Contract                     | Address                                      | Role                                                 |
| ---------------------------- | -------------------------------------------- | ---------------------------------------------------- |
| Safe (L1 singleton)          | `0x41675C099F32341bf84BFc5382aF534df5C7461a` | Safe master copy (mainnet-style)                     |
| SafeL2 (L2 singleton)        | `0x29fcB43b46531BcA003ddC8FCB67FFE91900C762` | Safe master copy emitting events for indexers        |
| SafeProxyFactory             | `0x4e1DCf7AD4e460CfD30791CCC4F9c8a4f820ec67` | Deploys Safe proxies (`createProxyWithNonce`)        |
| CompatibilityFallbackHandler | `0xfd0732Dc9E303f09fCEf3a7388Ad10A83459Ec99` | Default fallback handler (EIP-1271, token receivers) |
| MultiSend                    | `0x38869bf66a61cF6bDB996A6aE40D5853Fd43B526` | Batch multiple calls in one Safe tx                  |
| MultiSendCallOnly            | `0x9641d764fc13c8B624c04430C7356C1C7C8102e2` | Batch `CALL`-only txs (no delegatecall)              |
| CreateCall                   | `0x9b35Af71d77eaf8d7e40252370304687390A1A52` | Deploy contracts from within a Safe                  |
| SignMessageLib               | `0xd53cd0aB83D845Ac265BE939c57F53AD838012c9` | On-chain EIP-1271 message signing                    |
| SimulateTxAccessor           | `0x3d4BA2E0884aa488718476ca2FB8Efc291A46199` | `staticcall` tx simulation                           |

{% hint style="info" %}
On Gravity, point Safe proxies at the **SafeL2** singleton (`0x29fc…0C762`) rather than the L1 `Safe` — the L2 variant emits the events the Safe Transaction Service and indexers rely on.
{% endhint %}

## Verify before you hardcode

Confirm an address has code before relying on it:

```bash
cast code 0xcA11bde05977b3631167028862bE2a173976CA11 --rpc-url https://testnet-rpc.gravity.xyz
```

A non-empty result means the contract is live; an empty `0x` means it is not deployed yet.

# 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, and the optional `goal` query parameter:

```
GET https://docs.gravity.xyz/developer-resources/deployed-contracts-testnet.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
