What is a Token-Bound Account?

Every Gotchipus has its own on-chain wallet — a Token-Bound Account (TBA) created via the ERC-6551 standard. This means your Gotchipus isn’t just a token you own — it’s an entity that owns things itself.

​
How It Works

When you summon a Gotchipus, a TBA is automatically created using a deterministic Create2 factory. The TBA address is derived from:
  • The Gotchipus NFT’s token ID
  • The chain ID
  • A unique salt
This means the TBA address is predictable and permanent — your Gotchipus always has the same wallet address.

​
What Can a TBA Hold?

Your Gotchipus’s TBA can hold:
Asset TypeExamples
Native tokensPROS / ETH
ERC-20 tokensUSDC, USDT, WETH, WBTC
ERC-721 NFTsOther NFTs
ERC-1155 tokensWearables, consumables
The collateral you stake during summoning is sent directly to the TBA — your Gotchipus literally holds its own soul energy.

​
Execution

The TBA isn’t just a vault — it can execute transactions: 
Gotchipus Owner (or authorized Session)
  → executeAccount(tokenId, target, value, data)
    → BeforeExecute Hooks fire
      → TBA executes the transaction
        → AfterExecute Hooks fire
This execution flow is what makes autonomous behavior possible. Combined with Hooks and Sessions, your Gotchipus can interact with any smart contract on the network.

​
Who Can Execute?

ActorPermission
NFT OwnerFull execution rights
Authorized PaymasterCan sponsor and execute transactions
Active SessionCan execute within session constraints (time, value, whitelist)

​
Signature Validation

The TBA implements ERC-1271 (Standard Signature Validation), meaning it can verify signatures on behalf of the Gotchipus. This enables:
  • Off-chain message signing
  • Meta-transaction support
  • Protocol integrations that require signature verification

​
Why TBAs Matter

Without TBAs, a Gotchipus would be a token in your wallet, limited to what you do with it. With TBAs, a Gotchipus is an independent economic entity:
  • It owns its own assets
  • It can execute its own transactions
  • It has its own on-chain identity (address)
  • It can interact with DeFi protocols, marketplaces, and other contracts
This is the foundation that makes the vision of 20,000 autonomous agents possible. Each Gotchipus doesn’t just exist on-chain — it participates on-chain.
Reentrancy protection is built into the TBA execution flow. Each execution is guarded to prevent malicious reentrant calls.
