Deposit addresses · DAI

Dai deposit addresses for your users.

Give every one of your users a permanent Dai address they can deposit to any time. It has no private key, and we pay the network fee to collect what lands on it. MakerDAO's dollar, collateralised on-chain rather than by a bank account — the oldest stablecoin still in wide use.

Start building How deposit addresses works

DAI on 1 chain.

Enable the ones your users need. Each gives that user their own address, and enabling a new one later gives it to the users you already have.

EthereumERC-20

DAI on Ethereum: Gas here is the highest of any chain on this list, so a payment has to clear a minimum amount to be worth collecting. The checkout shows that minimum to your payer before they choose Ethereum, and every other chain here is cheaper.

Issuing a Dai address.

Create the customer
One POST with your own user id as the reference. This is the record everything else hangs off.
Ask for an address per chain
One per (customer, chain), and it does not change. The same customer has the same address on every EVM chain, and you can show it again tomorrow without calling us.
Credit on deposit.confirmed
We watch every block, credit what lands, and pay the network fee to move it. Nothing we do behind an address ever changes what you are owed.

POST /v1/customers

curl https://api.molnpay.com/v1/customers \
  -H "Authorization: Bearer $MOLNPAY_SECRET_KEY" \
  -H "Idempotency-Key: user_4471" \
  -d reference_id="user_4471"

What you do not have to do.

Hold a DAI wallet, or guard a seed phrase for one. No address here has a private key.
Keep gas on hand. We pay the network fee on every chain DAI settles on.
Re-issue an address. One per user, per chain, and it does not change.
Watch every block yourself, or reconcile a reorg by hand.
