One API. Vehicle identity, battery passports, charging payments, voice commands and fleet management — all on Ethereum. OEMs integrate once, unlock everything.
Eight production-ready modules covering the full EV lifecycle — accessible through a single authenticated API key.
Every vehicle gets a soulbound NFT minted to its owner. VIN hash stored on-chain, manufacturer data queryable. Tokens are locked by default — preventing unauthorized transfer while enabling permissioned access via TRANSFER_ROLE.
VehicleIdentity.sol GET /vehicles/:idImmutable battery health records anchored on-chain via Merkle roots. Oracles post state-of-health, cycle count, and degradation data. Full proof verification for regulatory compliance — EU Battery Regulation 2023/1542 ready.
BatteryPassport.sol GET /battery/:idPayment escrow for charging sessions. Funds locked at session start, released on completion. Supports ETH, USDC, and any ERC-20. 0.3% protocol fee auto-split between station operator and treasury. No chargebacks, no credit card rails.
ChargingPaymentRouter.sol POST /charging/sessionsDrop-in voice plugin for in-car middleware. Classifies natural language into payment intents and executes on-chain actions. Pre-built adapters for Tesla Grok, Alexa Auto, Google Assistant, and Apple Siri CarPlay.
@e-car-eth/voice-sdk POST /voice/intentEvery vehicle gets a smart account that autonomously pays for charging, tolls, and parking. Pre-authorized by the owner with configurable spending limits. No private key exposure — all operations via UserOps bundlers.
AgentWallet.sol ERC-4337 Account AbstractionAutomated carbon credit minting based on miles driven and kWh consumed. Credits are ERC-1155 tokens tradeable on any compatible marketplace. Retirement is recorded immutably for ESG reporting and corporate sustainability targets.
CarbonCreditMinter.sol GET /carbon/:idCommercial fleet operators register under fleet.e-car.eth. Add/remove vehicles, set geofence rules stored on-chain, and get aggregated payment summaries across charging, tolls, parking, and V2G earnings.
OEMs claim their subdomain under e-car.eth via a 10 ETH one-time fee. Deploys a dedicated BrandRegistry + 2-of-2 MultiSig granting full namespace control for vehicles, stations, and subnames.
NamespaceGovernorFactory.sol POST /brands/:brand/claimBidirectional energy settlement between EVs and grid operators. Vehicles earn USDC for exporting stored energy during peak demand. Settlement is automatic, per-kWh, with cryptographic proof of delivery via signed oracle data.
V2GSettlement.sol POST /v2g/settleCryptographic verification of over-the-air firmware updates. Hash + ECDSA signature verified on-chain before the ECU accepts an update. Prevents malicious firmware injection. Critical for ISO 21434 automotive cybersecurity compliance.
OTAVerifier.sol ECDSA + MerkleOn-chain risk pooling for EV-specific coverage. Premiums auto-calculated from battery health, mileage, and charging behavior. Claims triggered by oracle-attested events. Full transparency — no opaque actuarial black boxes.
InsuranceVault.sol Q2 2025Owners monetize anonymized telematics — battery cycles, driving patterns, route data. OEMs and researchers buy verified datasets via micropayments. Privacy-preserving: data sold as proofs, never raw telemetry.
DataMarketplace.sol Q3 2025From global OEMs to charging networks to fleet operators — neutral infrastructure anyone can build on.
Tesla pays 10 ETH to claim their namespace. All vehicles get minted as soulbound NFTs under *.tesla.e-car.eth. Battery passport data posted by Tesla's oracle. Voice SDK drops into FSD — drivers say "charge my car" and the agent wallet handles payment end-to-end.
A charging operator registers stations on-chain. EVs from any OEM with the protocol initiate sessions via API. Payment escrow locks funds, auto-releases on session close. Operator earns their rate minus 0.3% — no credit card rails, no chargebacks, no invoice cycles.
A logistics company's 500-EV fleet automatically mints carbon credits per kWh charged. Each credit is a verifiable ERC-1155 token with on-chain provenance. ESG team retires credits quarterly with immutable proof — ready for EU Taxonomy and SEC climate disclosure.
Fleet registers under fleet.e-car.eth. Each vehicle has geofence rules stored on-chain. Aggregated payment reports across all vehicles and all stations in a single API call. Real-time WebSocket alerts on vehicle status changes.
Grid operator signs V2G agreements with vehicle owners on-chain. During peak demand, participating EVs export energy and earn USDC automatically via V2GSettlement. Oracle attests kWh delivered. No invoicing — continuous micropayments per event.
An EV insurance startup queries battery health history via API, reads on-chain mileage, and prices premiums algorithmically. The InsuranceVault handles the risk pool. No need to build identity or data infrastructure — ship in weeks, not years.
From API key to first on-chain vehicle read in under 10 minutes.
Fill out the form below. Free tier gets 10K requests/month on Sepolia testnet. OEM tier unlocks mainnet access and production SLAs.
Use REST, GraphQL, or WebSocket. Full OpenAPI 3.0 spec at api.e-car.eth/docs. SDKs available for TypeScript and Python.
Call POST /brands/:brand/claim to get the unsigned transaction for your 10 ETH namespace claim. Sign with your OEM multisig.
Mint vehicle NFTs for your fleet via the API. Each gets a soulbound token, ENS subname, and battery passport slot — ready for data from day one.
Deployed on Ethereum Sepolia testnet. Source-verified on Etherscan. Auditable by anyone.
Drop @e-car-eth/voice-sdk into your in-car middleware. Natural language is classified into payment intents and executed via the vehicle's agent wallet — zero friction, no card swipe.
All tiers include Sepolia testnet access. Mainnet requires OEM or Enterprise.
Fees go to the protocol treasury and are separate from the API subscription.
Free tier available immediately for Sepolia testnet. OEM and Enterprise tiers reviewed within 1 business day.
