Bridge
bridge.l2.ippan.com
Deterministic cross-chain interoperability with attestation-backed asset bridging and supply reconciliation.
IPPAN Bridge is the subordinate interoperability layer for the IPPAN ecosystem. It is explicitly not a source of canonical truth — native asset ownership lives in rwa.l2.ippan.com. Instead, the bridge manages the lifecycle of wrapped representations on external EVM chains. Asset mappings define how each native IPPAN series maps to a wrapper contract on Ethereum, Polygon, Arbitrum, or Base, with support for ERC-20, ERC-721, ERC-1155, and ERC-3643 standards. Bridge workflows orchestrate multi-step operations: a lock-and-mint flow creates the flow record, runs compliance pre-flight checks (emergency state, mapping status, policy limits), generates lock and mint attestations with simulated transaction hashes, updates locked and minted supply on the mapping, and completes the flow — all within a single deterministic transaction. Burn-and-unlock reverses the process. Every operation is recorded in an append-only event log with SHA-256 proof hashes. Supply reconciliation reports compare locked vs minted supply per mapping and flag discrepancies. Emergency controls allow global bridge pauses, per-asset freezes, and route disabling with full audit trails.
Investor Lens
Expands distribution and liquidity access by making IPPAN assets interoperable across chains and execution environments.
Features
Key Capabilities
Asset Mapping & Wrapper Registry
Define how each native IPPAN asset series maps to a wrapped representation on external EVM chains. Supports ERC-20 (fungible), ERC-721 (certificates), ERC-1155 (multi-series), and ERC-3643 (regulated) standards across Ethereum, Polygon, Arbitrum, and Base.
Lock-and-Mint Workflow
Orchestrated multi-step flow: compliance pre-flight check, lock attestation on the native chain, supply update, mint attestation on the destination chain, supply update, and flow completion. Every step is recorded with deterministic event logging.
Burn-and-Unlock Workflow
Reverse bridge flow: burn the wrapped tokens on the external chain, reduce minted supply, unlock the native assets, reduce locked supply. Full attestation tracking and compliance validation at each stage.
Attestation Tracking
Every bridge operation generates cryptographic attestations (lock, mint, burn, unlock) with simulated transaction hashes, timestamps, and confirmation status. Attestations are linked to their parent flow for complete traceability.
Supply Reconciliation
On-demand reconciliation compares locked supply against minted supply for each asset mapping. Reports classify results as balanced, minor discrepancy, or critical discrepancy with percentage calculations.
Emergency Controls
Global bridge pause, per-asset freezes, and route disabling with full audit trails. Every emergency action records the operator, timestamp, reason, and creates a deterministic event log entry.
How It Works
Asset mapping links native series to external wrapper
An operator creates an asset mapping that defines the native IPPAN asset ID, the target external chain, the wrapper contract reference, the representation type (wrapped fungible, certificate, or mirror), and the EVM standard.
Bridge policy sets transfer rules
Each mapping has an associated policy defining direction (one-way lock, one-way mint, or two-way), compliance requirements, operator roles, and min/max amount limits.
Workflow engine orchestrates the bridge operation
A lock-and-mint or burn-and-unlock request triggers pre-flight checks (emergency state, mapping status, policy limits, supply availability), then executes the multi-step attestation flow atomically.
Attestations provide cryptographic proof
Each step generates a typed attestation (lock/mint/burn/unlock) with a transaction hash, chain references, and amount. Attestations are confirmed and linked to the parent flow.
Reconciliation verifies supply integrity
Reconciliation reports compare locked vs minted supply per mapping, calculate discrepancy percentages, and flag any imbalance. The event log captures every reconciliation run for audit.
