Connecting your wallet
When you click Connect wallet and approve the connection:- Dynamo reads your wallet address and on-chain balances.
- Dynamo cannot move your funds, sign transactions, or take any action on your behalf.
- You can disconnect your wallet at any time from within the app or your wallet’s connected sites settings.
Connecting a wallet is a read-only action. No funds can be moved until you explicitly sign a transaction.
Token approvals
Before you can deposit a token into a Morpho market or vault, you must grant the smart contract permission to spend that token.What it does
A token approval tells the ERC-20 token contract: “I allow this smart contract address to spend up to X amount of my tokens.”What to check
Always verify:- The contract address — confirm it matches the official Morpho contract for that market.
- The approval amount — Dynamo requests the minimum needed. Be cautious of unlimited approvals if you prefer to limit exposure.
Transaction signatures
Every action that changes your on-chain position requires you to sign a transaction:| Action | What you sign |
|---|---|
| Supply / deposit | Transfer tokens from your wallet to the Morpho contract |
| Borrow | Instruct the Morpho contract to send borrowed tokens to your wallet |
| Repay | Transfer tokens from your wallet back to the Morpho contract |
| Withdraw | Instruct the Morpho contract to return your supplied tokens |
| Vault deposit | Transfer tokens to the vault contract |
| Vault withdrawal | Redeem vault shares for underlying tokens |
Permit signatures (gasless approvals)
Some tokens support EIP-2612 permits, a type of off-chain signature that grants a spending approval without an on-chain transaction. Dynamo uses permits where available to save you gas.- Permit signatures look like a regular wallet pop-up but do not broadcast a transaction.
- They are single-use and expire after a short time window.
- They grant approval only for the specific action you are about to take.
Permit2
Dynamo also supports Permit2, Uniswap’s universal approval contract, for tokens that don’t natively support EIP-2612 permits.- Permit2 works as an intermediary: you grant a one-time approval to the Permit2 contract, then all subsequent per-action approvals are off-chain signatures.
- This means you only need one on-chain approval per token (to Permit2) instead of a separate on-chain transaction for every new protocol you use.
- Individual action permits are still single-use and time-limited, just like EIP-2612 permits.
Permit2 approvals are to the Permit2 contract address (
0x000000000022D473030F116dDEE9F6B43aC78BA3), not directly to Morpho or Dynamo contracts.Morpho Bundler Authorization
For more complex multi-step transactions (e.g., supplying collateral and borrowing in a single click), Dynamo uses the Morpho Bundler, a smart contract that batches multiple Morpho operations into one transaction. To use the bundler, you grant it a one-time authorization in Morpho’s contract. This authorization allows the bundler to act on your behalf within Morpho for the duration of a batched transaction. Key points:- The authorization is scoped to the bundler contract address only.
- It does not give the bundler (or Dynamo) ongoing access to move your funds at will, each bundled transaction still requires your signature.
- You can revoke bundler authorization at any time by calling the Morpho contract directly or using a supported revocation tool.
| Permission type | On-chain? | Scope |
|---|---|---|
| Wallet connection | No | Read-only |
| ERC-20 token approval | Yes | Specific contract, specific token |
| Permit2 approval | Yes (one-time) | Permit2 contract for a specific token |
| EIP-2612 / Permit2 action permit | No | Single action, time-limited |
| Morpho bundler authorization | Yes (one-time) | Batched operations via bundler |
What Dynamo can never do
- Move funds without your explicit signature on each transaction.
- Change your wallet’s private keys or seed phrase.
- Access wallets you have not connected.
- Override or cancel a transaction once it is confirmed on-chain.
Revoking approvals
If you want to remove a previously granted token approval, you can do so using any token approval management tool (such as revoke.cash):- Connect your wallet to the approval manager.
- Find the approval for the relevant Morpho contract.
- Submit a revocation transaction (requires a small gas fee).
