Transaction Format

ErgoScript transactions follow a specific format that wallets must understand to properly construct and process transactions. This includes input/output structures, script serialization, and metadata handling.
  • Transaction input and output structures
  • ErgoScript serialization formats
  • Metadata and extension handling
  • Version compatibility and upgrades

Merkle Tree Verification

Merkle trees provide efficient cryptographic verification for wallet operations. Wallets use Merkle proofs to verify transaction inclusion and state transitions without downloading the entire blockchain.
  • Merkle proof generation and verification
  • Light client support and SPV
  • State tree verification
  • Efficient batch verification

Digital Signing

Wallets implement sophisticated signing mechanisms to generate cryptographic proofs for ErgoScript contracts. This includes support for various signature schemes and multi-signature protocols.
  • Schnorr signature generation
  • Multi-signature and threshold schemes
  • Zero-knowledge proof generation
  • Hardware wallet integration

Signing Backend Infrastructure

Backend services that support wallet signing operations, including key management systems, signing services, and secure enclaves for enterprise and custodial solutions.
  • Secure key storage and management
  • HSM and secure enclave integration
  • Multi-party computation (MPC)
  • Audit and compliance features

Transaction Validation

Comprehensive validation processes that wallets perform to ensure transaction integrity, script correctness, and network compliance before broadcasting transactions.
  • ErgoScript contract validation
  • Input/output consistency checks
  • Fee validation and optimization
  • Network rule compliance

Data Input Processing

Data inputs provide read-only access to blockchain state for smart contracts. Wallets must properly handle data input selection, validation, and integration with transaction construction.
  • Data input selection strategies
  • Oracle data integration
  • State snapshot handling
  • Privacy-preserving data access

Fee Management

Intelligent fee calculation and management strategies for optimal transaction processing. Includes dynamic fee estimation, fee optimization, and user experience considerations.
  • Dynamic fee estimation algorithms
  • Priority-based fee strategies
  • Batch transaction optimization
  • Fee-less transaction patterns

Unified Transaction Standards

Standardized transaction formats that enable interoperability between different wallet implementations and cross-chain protocols. Ensures consistent behavior across the ecosystem.
  • Cross-wallet compatibility standards
  • Bridge transaction formats
  • Atomic swap implementations
  • Protocol upgrade mechanisms
