On-Chain Credit Systems vs. Off-Chain Voucher Systems

Unprecedented Composability: Native smart contract integration with protocols like Aave, Compound, and MakerDAO. Enables flash loans, automated collateral management, and permissionless innovation.

Transparent & Auditable: All credit positions, risk parameters, and liquidations are publicly verifiable on-chain. This reduces counterparty risk and builds trustless systems.

Global Settlement Finality: Credit issuance and repayment are settled on the base layer (e.g., Ethereum, Solana), providing cryptographic finality and eliminating off-chain reconciliation.

Limited by Collateral: Most systems (e.g., over-collateralized loans on Maker) require 150%+ collateral ratios, restricting capital efficiency.

High On-Chain Costs: Minting and managing credit positions incur gas fees, making micro-transactions (e.g., in-game credits) prohibitively expensive on L1s.

Privacy Challenges: All financial relationships are public, a non-starter for many institutional and B2B use cases requiring confidentiality.

High Throughput & Low Cost: Voucher issuance and redemption can be batched, enabling massive scale for gaming (e.g., Immutable X marketplaces) and loyalty programs with sub-cent fees.

Flexible Credit Models: Supports under-collateralized lending, KYC-gated credit lines, and complex business logic managed off-chain by entities like Centrifuge or traditional fintech rails.

Regulatory Clarity: The voucher itself can be a regulated digital asset (security token) while the underlying credit agreement remains in a compliant, off-chain legal framework.

Custodial & Centralized Risk: Relies on a trusted issuer (e.g., a company or DAO) to honor redemption. Creates single points of failure and requires legal recourse.

Reduced Composability: Vouchers (ERC-20 tokens) can be traded on DEXs, but the underlying credit logic is opaque and cannot be natively integrated into DeFi money markets without wrappers.

Settlement Friction: Final settlement requires interacting with an off-chain system, introducing latency and potential disputes not present in pure on-chain systems.

Settlement Finality & Composability: Credit positions (e.g., Aave debt, Compound collateral) are native on-chain assets. This enables trustless composability with DeFi protocols like Uniswap for liquidation or Yearn for yield strategies without bridging.

Universal Auditability: Every transaction and state change is recorded on a public ledger (Ethereum, Arbitrum). This is critical for regulated financial applications or protocols requiring transparent, immutable audit trails for liabilities.

High & Volatile Gas Costs: Every interaction—minting, transferring, repaying—incurs network fees. On Ethereum L1, this can cost $10-$100+ per tx, making micro-transactions or frequent state updates economically unviable.

Limited Privacy & Speed: All data is public. Settlement speed is bound to block times (e.g., 12 sec on Ethereum, 2 sec on Solana), creating latency for real-time point-of-sale or high-frequency use cases.

Near-Zero Transaction Cost & Instant Settlement: Vouchers are issued and redeemed off-chain (e.g., via centralized databases or Layer 2 state channels). This enables high-frequency, low-value transactions like in-game micro-payments or loyalty points with sub-second finality and negligible fees.

Flexible Privacy & Compliance: Issuers (like Starbucks or airline miles programs) control data visibility and can integrate KYC/AML gates at redemption without exposing all user activity on a public blockchain.

Issuer Counterparty Risk & Fragmentation: Value is an IOU from the issuing entity. Users bear custodial risk (e.g., issuer insolvency). Systems are siloed; a Starbucks voucher cannot be natively used in a Nike ecosystem without a centralized bridge.

Reduced DeFi Composability: Off-chain vouchers are not native crypto assets. They cannot be directly used as collateral on MakerDAO, traded on Uniswap, or bundled into yield-bearing strategies without a custodial wrapping service, which reintroduces trust.
