Ethereum's transaction ecosystem has evolved dramatically since its inception, but one persistent challenge remained: the fragmented process of executing multiple blockchain operations. EIP 5792, officially known as the Wallet Call API, represents a fundamental shift in how applications communicate with wallets to enable batch transactions, atomic execution, and enhanced user experiences across the Ethereum ecosystem.
What is EIP 5792?
EIP 5792 defines new JSON-RPC methods that enable applications to request wallets to process multiple onchain write calls in a single batch and monitor their execution status. This proposal introduces wallet_sendCalls, wallet_getCallsStatus, wallet_showCallsStatus, and wallet_getCapabilities methods that modernize wallet-application communication.
The specification addresses a core limitation in traditional Ethereum transactions: the inability to efficiently execute multiple related operations without risking partial failures or excessive gas costs. By introducing standardized batch transaction capabilities, EIP 5792 enables developers to build more sophisticated applications while reducing user friction.
Core Components and JSON-RPC Methods
wallet_sendCalls: The Foundation of Batch Execution
The wallet_sendCalls method serves as the cornerstone of EIP 5792's functionality. Applications can submit multiple transaction calls in a single request, with the wallet determining whether to execute them atomically or sequentially based on its capabilities.

}
]
}]
}wallet_getCallsStatus: Real-Time Transaction Monitoring
The wallet_getCallsStatus method provides real-time tracking of batch execution status. Applications can monitor whether calls are executed atomically, individually, or encounter failures through detailed status responses.
wallet_showCallsStatus: User-Controlled Transparency
This method enables applications to request wallets to display batch status information directly to users, improving transparency and user control over complex transactions.
wallet_getCapabilities: Dynamic Feature Discovery
The wallet_getCapabilities method allows applications to query whether wallets support specific features like atomic batch transactions for particular addresses and chain IDs. This capability discovery mechanism enables adaptive application behavior based on wallet functionality.
Atomic vs Sequential Batch Execution
Understanding Atomic Transactions
Atomic execution guarantees that either all transactions in a batch succeed or none execute at all. This eliminates scenarios where users pay gas fees for partial transaction successes, such as approved tokens with failed swaps.
For example, in a typical token swap scenario:
Traditional approach: User approves token spending (Transaction 1), then executes swap (Transaction 2)
EIP 5792 atomic approach: Both operations execute together or fail together
Sequential Batch Processing
Sequential execution allows individual transactions within a batch to fail independently while still providing gas optimization benefits through bundled submission.
Gas Optimization and Economic Benefits
EIP 5792 provides substantial economic advantages beyond improved user experience. Each transaction on Ethereum costs 21,000 gas as a base fee, meaning batching 10 transactions can save 189,000 gas total.
Cost-Benefit Analysis
Traditional multi-step flows often leave users with:
Failed transactions consuming gas without completion
Multiple confirmation steps requiring user attention
Higher total gas costs due to individual transaction overhead
Batch transactions eliminate these inefficiencies by:
Reducing base transaction fees through consolidation
Enabling more sophisticated trading strategies
Making complex DeFi interactions cost-effective
Integration with Modern Wallet Infrastructure
Smart Contract Wallet Compatibility
EIP 5792 elevates smart contract wallets to first-class citizens alongside EOAs, with smart wallets offering superior UX through one-click transactions without sacrificing compatibility.
Major wallet implementations include:
Coinbase Smart Wallet: Native EIP 5792 integration
WalletConnect: Full specification support across connected applications
ERC-4337 Account Abstraction Synergy
EIP 5792 works seamlessly with ERC-4337 account abstraction infrastructure. ERC-4337 enables custom verification logic, meta transactions, and batch operations through smart contract accounts, while EIP 5792 provides the standardized interface for applications to request these capabilities.
Real-World Applications and Use Cases
DeFi Protocol Interactions
Complex DeFi strategies become practical with atomic execution guarantees:
Liquidity provisioning: Approve tokens, add liquidity, and stake LP tokens atomically
Yield farming: Harvest rewards, compound earnings, and reinvest across protocols
Governance participation: Execute governance proposals with fund transfers and parameter updates
Cross-Chain Operations
Layer 2 networks like Base, Optimism, and Arbitrum are implementing native EIP 5792 support, providing cost-effective batch execution environments. This enables:
Bridge operations with immediate destination chain interactions
Multi-chain portfolio rebalancing
Cross-chain arbitrage execution
Enterprise and Institutional Use Cases
Atomic transactions reduce operational risks in high-value institutional DeFi use cases, enabling:
Treasury management with multi-signature approvals
Compliance-friendly transaction execution
Risk management through guaranteed operation completion
Developer Implementation Guide
Using thirdweb Connect SDK
thirdweb's Connect SDK provides comprehensive EIP 5792 support with automatic fallback to legacy methods when wallets don't support the specification:
typescript
import { sendCalls, getCapabilities } from "thirdweb/wallets/eip5792";
// Send atomic batch
const { bundleId } = await sendCalls({
calls: [approveCall, swapCall],
capabilities: { paymasterService: true }
});
// Track status const
status = await getCallsStatus({ bundleId });React Integration Patterns
Frontend integration becomes streamlined with pre-built hooks:
typescript
const { mutate: sendCalls } = useSendCalls();
const { data: status } = useCallsStatus({ bundleId });Capability Detection and Graceful Degradation
Applications should implement capability detection for optimal user experience:
typescript
const capabilities = await wallet.getCapabilities();
const atomicSupported = capabilities?.[chainId]?.atomic?.status === 'supported';
if (atomicSupported) {
// Use batch transactions
} else {
// Fall back to sequential transactions
}
Security Considerations and Best Practices
Batch Identifier Security
Wallets must ensure that batch identifiers returned by wallet_sendCalls are unpredictable to prevent malicious applications from inferring information about other users' transactions.
Privacy Protection
Wallets must not leak sensitive information in wallet_getCallsStatus capabilities responses, maintaining user privacy while providing necessary functionality.
Application Security Guidelines
Developers should implement:
Proper error handling for failed batch transactions
Capability validation before attempting batch operations
User confirmation for high-value atomic transactions
Network Support and Adoption Status
Layer 2 Implementation
Base and other Layer 2 solutions have integrated EIP 5792 support, with Smart Wallet submitting multiple calls as part of single transactions. This provides:
