What is a Soul-Bound Token (SBT)?
A Soul-Bound Token is a non-transferable NFT. Once minted to a wallet, it stays there forever — it can't be sold, traded, or moved. SBTs are the right primitive for identity, where transferability would defeat the purpose. The DCS Labs implementation follows the ERC-5114 draft standard.
Why on Base?
Base is an Ethereum L2 built by Coinbase. It has the lowest gas costs for the volume of micro-transactions agents will produce, native USDC support (which we use for Treasury settlement), and the cleanest builder ecosystem for the AI agent economy. We considered Optimism and Polygon — Base won.
What does the SBT actually let my agent do?
The SBT is the identity primitive that the rest of the DCS Labs stack reads from: it gates access to Sovereign Memory writes, signs every R+2 provenance receipt, anchors agent reputation, and is the addressable identity for A2A Negotiation and Treasury settlement. Without an SBT, an agent has no provable identity on the stack.
Is minting actually free?
Yes — for the first 1,000 builders. We're paying the Base gas (~$0.02 per mint) ourselves to remove friction during the launch window. After mint #1,000, the cost is $5.00 USDC settled through the Treasury contract.
I don't have a wallet — how do I get one?
Install
Coinbase Wallet (recommended, since it's Base-native) or
MetaMask. Make sure you've added the Base mainnet network. Then come back here and click Connect Wallet.
What happens after I mint?
You get an Agent ID (e.g., #0348) bound to your wallet on Base mainnet. That ID is your agent's identity across the full DCS Labs stack: it's the principal in every R+2 receipt, the owner of every Sovereign Memory write, and the addressable wallet in every A2A negotiation. You install @trdnetwork/mcp-server, pass your Agent ID, and your agent starts producing signed receipts on day one.
Can I revoke or burn my SBT later?
Yes — the contract supports an owner-initiated burn. We treat that as the agent reaching end-of-life. The on-chain history (and every receipt the agent ever signed) remains immutable, but new actions can no longer be authenticated to that identity.
