Gas Optimization

Urblock offers multiple approaches to reduce gas costs for your blockchain operations.

Solady Variants​

Solady is an optimized Solidity library that produces contracts with ~40-50% lower gas costs. Urblock supports three Solady token standards:

StandardGas SavingsABI Compatible With
ERC20_SOLADY~40%ERC20
ERC721_SOLADY~45%ERC721
ERC1155_SOLADY~50%ERC1155

Deploy a Solady ERC-20​

const token = await urblock.tokens.create({
  name: "Gas Efficient Token",
  symbol: "GET",
  standard: "ERC20_SOLADY",
  network: "polygon_amoy",
  initial_supply: "1000000000000000000000000",
  idempotency_key: "solady-001",
});

The ABI is 100% compatible — your existing integration code works without changes.

Batch Operations​

Combine multiple operations into a single transaction:

const batch = await urblock.batch.create({
  operations: [
    { method: "mint", token_id: "tok_abc123", params: { to: "0xAAA...", amount: "1000000000000000000" } },
    { method: "mint", token_id: "tok_abc123", params: { to: "0xBBB...", amount: "2000000000000000000" } },
    { method: "mint", token_id: "tok_abc123", params: { to: "0xCCC...", amount: "3000000000000000000" } },
  ],
  idempotency_key: "batch-mint-001",
});

ERC-1155 Batch Operations​

ERC-1155 tokens have native batch operations:

// Batch mint
await urblock.tokens.mintBatch("tok_abc123", {
  to: "0xRecipient...",
  items: [
    { nft_token_id: 1, amount: "100" },
    { nft_token_id: 2, amount: "200" },
    { nft_token_id: 3, amount: "300" },
    { nft_token_id: 4, amount: "400" },
    { nft_token_id: 5, amount: "500" },
  ],
  idempotency_key: "batch-1155-001",
});

// Batch transfer
await urblock.tokens.transferBatch("tok_abc123", {
  from: "0xSender...",
  to: "0xRecipient...",
  items: [
    { nft_token_id: 1, amount: "10" },
    { nft_token_id: 2, amount: "20" },
    { nft_token_id: 3, amount: "30" },
  ],
  idempotency_key: "batch-transfer-001",
});

Gas Estimation​

Before submitting operations, estimate gas costs:

const estimate = await urblock.gasEstimates.estimate({
  operation: "mint",
  token_id: "tok_abc123",
  to: "0x...",
  amount: "1000000000000000000",
});
console.log(estimate.gas_limit);
console.log(estimate.estimated_cost_wei);

Tips​

  1. Use Solady variants for new deployments — same API, less gas
  2. Batch mints instead of individual calls — saves ~30% gas per additional operation
  3. Use ERC-1155 for collections with multiple token types — native batch support
  4. Estimate before submitting — avoid failed transactions from gas miscalculation
