CBSA Tokenization & Digital Assets 2 — Questions and Answers
Question 1: What is a stablecoin collateralization ratio, and why is it critical in DeFi?
- The ratio of stablecoins to volatile tokens in a wallet
- The amount of collateral held relative to the value of stablecoins issued, ensuring solvency (Correct answer)
- The exchange rate between two stablecoins
- The ratio of on-chain to off-chain stablecoin transactions
Correct answer: The amount of collateral held relative to the value of stablecoins issued, ensuring solvency
Collateralization ratio measures how much collateral backs each issued stablecoin; ratios above 100% (overcollateralization) protect against price volatility and prevent insolvency.
Question 2: Which type of oracle is most appropriate for providing real-world asset prices to a token smart contract?
- On-chain oracle
- Centralized off-chain oracle
- Decentralized oracle network (Correct answer)
- Block timestamp oracle
Correct answer: Decentralized oracle network
Decentralized oracle networks like Chainlink aggregate data from multiple sources, eliminating single points of failure and manipulation when feeding asset prices to smart contracts.
Question 3: What is the purpose of a token vesting schedule in a blockchain project?
- To increase token supply over time based on inflation
- To gradually release tokens to founders and investors over time, aligning long-term incentives (Correct answer)
- To lock tokens as collateral for loans
- To automate token burns at regular intervals
Correct answer: To gradually release tokens to founders and investors over time, aligning long-term incentives
Vesting schedules release tokens incrementally over a defined period, preventing early holders from dumping all tokens at once and ensuring alignment with project success.
Question 4: In a security token offering (STO), what is the role of a transfer agent on the blockchain?
- To mine new security tokens
- To enforce compliance rules such as KYC/AML whitelists during token transfers (Correct answer)
- To convert security tokens to utility tokens
- To set the token price during secondary trading
Correct answer: To enforce compliance rules such as KYC/AML whitelists during token transfers
A blockchain-based transfer agent enforces regulatory compliance by checking whitelisted addresses and transfer restrictions embedded in the security token smart contract before any transfer executes.
Question 5: What is 'wrapping' a token (e.g., Wrapped Bitcoin / WBTC)?
- Encrypting a token for private transfers
- Creating a new token on a different blockchain that is backed 1:1 by the original asset (Correct answer)
- Combining multiple tokens into a single derivative
- Adding metadata to an existing token standard
Correct answer: Creating a new token on a different blockchain that is backed 1:1 by the original asset
Wrapped tokens represent a cross-chain asset, where the original token is locked in a custodian or smart contract and a pegged equivalent is minted on the target chain.
Question 6: Which architecture pattern best supports a regulated tokenized real estate platform requiring investor accreditation checks?
- Fully public permissionless token on Ethereum mainnet with no transfer restrictions
- ERC-1400 security token standard with permissioned transfers and on-chain compliance modules (Correct answer)
- ERC-20 token with off-chain compliance checks only
- NFT-based system with open marketplace trading
Correct answer: ERC-1400 security token standard with permissioned transfers and on-chain compliance modules
ERC-1400 (or ERC-1404) security token standards embed transfer restriction logic on-chain, enabling automated accreditation and jurisdiction checks at the contract level.
