Deployments

The protocol is deployed on the Sepolia testnet. Addresses are recorded in scripts/deployments.json.

Sepolia addresses

Contract	Address	Role
`Factory`	`0xadeb683e2c28514b89e600a0cd50185254b2d7f3`	CREATE2 deployer
`Token` (DPC)	`0x6d663c7c401a18208748dF6F909ffc0C68FA1B73`	Protocol-native token
`FeeController`	`0xe091dD90A4a3e0ed43fEd2D85A0fD043823B4648`	Manages protocol fees
`DataPrism`	`0x2614B6E7F2134FBD880c88BAB10412b046a11211`	Core storage
`DataPrismCloud`	`0x7fEda6645CDdDd193d6bEFAB7367c98C30d62469`	Application layer
`DataPrismCloudForwarder`	`0x6f01C6E81ae6Adac1471B3Ce4000a3CC812438dF`	EIP-712 meta-transactions
`Exchange`	`0x0Cc50006445C7E0e08Fb46Bf5d8b1bECf5275Ba1`	DPC exchange

External token used by the Exchange (not deployed by the protocol):

Token	Address
USDC (Sepolia)	`0xC6a054681bEBb1096BB03E3Fc433bD99BAe987d0`

The Exchange is configured with a USDC rate of 1000 × 10^12 (1 USDC → 1000 DPC).

Deployment configuration

Configured in scripts/deploy.ts:

const RPC_URL = "https://ethereum-sepolia-rpc.publicnode.com";
const EXTERNAL = { usdc: "0xC6a054681bEBb1096BB03E3Fc433bD99BAe987d0" };
const USDC_RATE = 1000n * 10n ** 12n; // 1 USDC (6 decimals) → 1000 DPC (18 decimals)

Each contract is deployed via the Factory using a deterministic CREATE2 salt (salts 0-6 in SALTS). The deployer (PRIVATE_KEY) is passed as initialOwner to each contract.

Deployment sequence

0. Factory                                ← deployed via regular CREATE
1. Token(initialOwner)                     ← Factory CREATE2, salt 1
2. FeeController(initialOwner)             ← Factory CREATE2, salt 2
3. DataPrism(Token, FeeController)         ← Factory CREATE2, salt 3
4. Exchange(Token, FeeController, owner)   ← Factory CREATE2, salt 4
5. DataPrismCloud(DataPrism, owner)        ← Factory CREATE2, salt 5
6. DataPrismCloudForwarder(Cloud, owner)   ← Factory CREATE2, salt 6
7. Wire: DataPrismCloud.setForwardContract(Forwarder)
8. Configure Token permissions (operator, minter, burner)
9. Configure Exchange (accept USDC)
10. Set DataPrismCloud custom fees in FeeController (creation → 1000 DPC / 1 USDC, data operations → 100 DPC / 0.1 USDC each, other prism operations → 0)

Post-deployment setup

Run manually from the deployer account:

// 1. Set the protocol fee treasury (defaults to deployer)
FeeController.setTreasury(treasuryAddress);
 
// 2. Set the relayer commission treasury (non-official relayer share)
DataPrismCloudForwarder.setProtocolTreasury(treasuryAddress);
 
// 3. Whitelist at least one official relayer
DataPrismCloudForwarder.setOfficialRelayer(relayerAddress, true);
 
// 4. Set the priority window (seconds of exclusive official-relayer access)
DataPrismCloudForwarder.setPriorityWindow(60);
