Deployed contracts

These public addresses were checked against each configured network on 12 October 2026. Each network uses the same configured addresses; deployed code and availability differ by network.

Contract	Address
Factory	`0x4Ac838b970D44AB9056b4201e9ED3c1Ce271545e`
Remix	`0xC5c7d2645A7119b538C8d752Ce61c9706cDF7A36`
Royalties	`0xff402e0C8c9a19f855200524260A858DDF99EdcD`

Use these addresses with the network you select for your RPC and wallet clients.

Network	Chain ID	Factory	Remix	Royalties
Arbitrum Sepolia	`421614`	Present	Present	Present
Base Sepolia	`84532`	Present	Present	Present
Tempo Moderato	`42431`	Present	Present	Present
Robinhood testnet	`46630`	Present	No code	Present
Arbitrum One	`42161`	No code	No code	No code
Base	`8453`	No code	No code	No code
Tempo	`4217`	No code	No code	No code
Robinhood mainnet	`4663`	No code	No code	No code

“Present” means eth_getCode returned contract code at the address. “No code” means it returned 0x at the checked block. These checks do not certify that source code has been verified on an explorer. Use Arbitrum Sepolia, Base Sepolia or Tempo Moderato for the complete contract interface. Robinhood testnet does not have Remix at the configured address, so license and variation calls through that address are unavailable.

License settlement tokens

The complete deployments returned matching Remix.factory() and Remix.royalties() references, and Factory recognized Remix as an authorized consumer. Royalties returned these six-decimal tokens:

Network	Token	Address
Arbitrum Sepolia	USDC	0x75faf114eafb1BDbe2F0316DF893fd58CE46AA4d
Base Sepolia	USDC	0x036CbD53842c5426634e7929541eC2318f3dCF7e
Tempo Moderato	OUSD	0x20c0000000000000000000006a37DA5C996874BE

Always read Royalties.usdc() before an approval. Its name does not guarantee that every network uses USDC.

Check your connection

export RPC_URL=https://sepolia-rollup.arbitrum.io/rpc
cast chain-id --rpc-url "$RPC_URL"
cast code 0x4Ac838b970D44AB9056b4201e9ED3c1Ce271545e --rpc-url "$RPC_URL"
cast call 0xC5c7d2645A7119b538C8d752Ce61c9706cDF7A36 'factory()(address)' --rpc-url "$RPC_URL"
cast call 0xff402e0C8c9a19f855200524260A858DDF99EdcD 'usdc()(address)' --rpc-url "$RPC_URL"

These are read-only calls. Expect chain ID 421614, nonempty Factory code, and the Factory and token addresses listed above. Repeat the checks for your selected network before requesting a wallet transaction.
