Operator-Style API

gte mimics the >= operator for clearer code:

import { CANCUN, LONDON } from 'tevm'

// Operator-style (reads like >= operator)
if (CANCUN.gte(LONDON)) {
  // ...
}

// Equivalent semantic form
if (CANCUN.isAtLeast(LONDON)) {
  // ...
}

Usage Patterns

Feature Gating

import { Hardfork, LONDON } from 'tevm'

const fork = Hardfork(config.hardfork)

if (fork.gte(LONDON)) {
  // EIP-1559 available
}

Network Configuration

import { Hardfork, SHANGHAI } from 'tevm'

function validateVersion(fork: BrandedHardfork) {
  if (!fork.gte(SHANGHAI)) {
    throw new Error("Requires Shanghai or later")
  }
}

Chronological Ordering

Uses chronological deployment order:

FRONTIER (0) < HOMESTEAD (1) < ... < CANCUN (16) < PRAGUE (17)

Performance

Time Complexity: O(1) - Array index comparison

Typical Time: ~10-20ns per call
