Configuration

Setting	Value
Chain	Base Sepolia (84532)
EAS Contract	`0x4200000000000000000000000000000000000021`
Attester Address	`0x590fdb53ed3f0B52694876d42367192a5336700F`

Example Request

curl -X POST https://staging-api.astral.global/compute/v0/distance \
  -H "Content-Type: application/json" \
  -d '{
    "chainId": 84532,
    "from": {"type": "Point", "coordinates": [-122.4194, 37.7749]},
    "to": {"type": "Point", "coordinates": [-73.9352, 40.7128]}
  }'

chainId only tells the service which EAS chain to format the delegated attestation for, so the result could be submitted onchain later. Nothing here touches a blockchain unless you choose to submit the result yourself — the call above just returns a signed result.

Verifying signatures

What a matching signature proves. Checking the attester address proves the result was signed by a key Astral controls. It does not, on its own, prove the result was produced inside an independently attested TEE enclave: Astral has run the service on real TEE hardware in test deployments but does not currently fund continuous attested operation. Treat the staging signer as “Astral’s staging key,” not as a hardware-attestation guarantee. To evaluate against real TEEs, reach out at contact@astral.global.

All attestations from the staging service are signed by the attester address above. To verify a result came from Astral’s staging environment:

require(attestation.attester == 0x590fdb53ed3f0B52694876d42367192a5336700F, "Not from Astral staging");

const ASTRAL_STAGING_SIGNER = '0x590fdb53ed3f0B52694876d42367192a5336700F';
// Verify the EAS attestation's attester field matches

Notes

No authentication required
Rate limited to 100 requests/hour per IP
Attestations are signed with the staging key — a different key will be used for production
