Add Fantom Method Spec

[themetalfleece]

Add fantom.json spec with chain-specific methods.

Validation

chains.yaml:

    - id: fantom
      label: Fantom
      type: eth
      settings:
        method-spec: "fantom" # this needs to be added to the upstream

nodecore.yml:

  upstreams:
    - id: public-fantom
      chain: fantom-testnet
      connectors:
        - type: json-rpc
          url: https://rpc.testnet.fantom.network

Invoking the methods:

URL="http://localhost:9090/queries/fantom-testnet"
EPOCH=$(curl -s -X POST $URL -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"ftm_currentEpoch","params":[],"id":1}' | jq -r '.result')
echo "Current epoch: $EPOCH"
echo ""

echo "=== ftm_effectiveBaseFee ==="
curl -s -X POST $URL -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"ftm_effectiveBaseFee","params":[],"id":1}' | jq .
echo ""

echo "=== ftm_currentEpoch ==="
curl -s -X POST $URL -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"ftm_currentEpoch","params":[],"id":1}' | jq .
echo ""

echo "=== ftm_getEpochBlock (epoch: $EPOCH) ==="
curl -s -X POST $URL -H "Content-Type: application/json" -d "{\"jsonrpc\":\"2.0\",\"method\":\"ftm_getEpochBlock\",\"params\":[\"$EPOCH\"],\"id\":1}" | jq .
echo ""

echo "=== ftm_getRules (epoch: $EPOCH) ==="
curl -s -X POST $URL -H "Content-Type: application/json" -d "{\"jsonrpc\":\"2.0\",\"method\":\"ftm_getRules\",\"params\":[\"$EPOCH\"],\"id\":1}" | jq .
echo ""

echo "=== ftm_getEpochStats (latest) ==="
curl -s -X POST $URL -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"ftm_getEpochStats","params":["latest"],"id":1}' | jq .

Sample output:
