Protocol Support

This guide explains how to configure ABI generation for specific blockchain protocols, including Ethereum, NEAR, ICP, and Starknet.

Overview​

Calimero's ABI generation supports multiple blockchain protocols, each with its own specific requirements and optimizations.

Ethereum Support​

Configuration​

use calimero_abi_emitter::{calimero_app, Protocol, ProtocolFeatures};

#[calimero_app(
    protocol = Protocol::Ethereum,
    features = [
        ProtocolFeatures::GasOptimization,
        ProtocolFeatures::EventLogging
    ]
)]
pub struct EthereumApp {
    // Ethereum-specific application
}

Type Mappings​

Ethereum-specific type mappings and optimizations.

NEAR Support​

Configuration​

use calimero_abi_emitter::{calimero_app, Protocol, ProtocolFeatures};

#[calimero_app(
    protocol = Protocol::NEAR,
    features = [
        ProtocolFeatures::AccountOptimization,
        ProtocolFeatures::StorageOptimization
    ]
)]
pub struct NearApp {
    // NEAR-specific application
}

ICP Support​

Configuration​

use calimero_abi_emitter::{calimero_app, Protocol, ProtocolFeatures};

#[calimero_app(
    protocol = Protocol::ICP,
    features = [
        ProtocolFeatures::CanisterOptimization,
        ProtocolFeatures::CycleOptimization
    ]
)]
pub struct IcpApp {
    // ICP-specific application
}

Starknet Support​

Configuration​

use calimero_abi_emitter::{calimero_app, Protocol, ProtocolFeatures};

#[calimero_app(
    protocol = Protocol::Starknet,
    features = [
        ProtocolFeatures::CairoOptimization,
        ProtocolFeatures::AccountAbstraction
    ]
)]
pub struct StarknetApp {
    // Starknet-specific application
}

Multi-Protocol Support​

Configure your application to support multiple protocols:

use calimero_abi_emitter::{calimero_app, Protocol, ProtocolConfig};

#[calimero_app(
    protocols = [Protocol::Ethereum, Protocol::NEAR, Protocol::ICP, Protocol::Starknet],
    protocol_config = ProtocolConfig {
        ethereum: EthereumConfig {
            gas_optimization: true,
        },
        near: NearConfig {
            account_optimization: true,
        },
        icp: IcpConfig {
            canister_optimization: true,
        },
        starknet: StarknetConfig {
            cairo_optimization: true,
        },
    }
)]
pub struct MultiProtocolApp {
    // Multi-protocol application
}
