## Logo Download Script
|
|
|
|
Use this script to download logos from Trust Wallet assets:
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
# Download token logos from Trust Wallet assets
|
|
|
|
TOKENS=(
|
|
"0xdAC17F958D2ee523a2206206994597C13D831ec7:cusdt"
|
|
"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48:cusdc"
|
|
"0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2:weth"
|
|
)
|
|
|
|
for token in "${TOKENS[@]}"; do
|
|
IFS=':' read -r address name <<< "$token"
|
|
url="https://raw.githubusercontent.com/trustwallet/assets/master/blockchains/ethereum/assets/$address/logo.png"
|
|
wget -O "$name.png" "$url" || echo "Failed to download $name"
|
|
done
|
|
```
|
|
|
|
## Blockscout Configuration
|
|
|
|
Add to Blockscout configuration:
|
|
|
|
```elixir
|
|
config :blockscout_web, BlockscoutWeb.Endpoint,
|
|
logo_serving: [
|
|
enabled: true,
|
|
base_path: "/images/tokens",
|
|
fallback_logo: "/images/default-token.png"
|
|
]
|
|
```
|
|
|
|
## Verification
|
|
|
|
Test logo URLs:
|
|
|
|
```bash
|
|
# Test cUSDT logo
|
|
curl -I https://explorer.d-bis.org/images/tokens/0x93E66202A11B1772E55407B32B44e5Cd8eda7f22.png
|
|
|
|
# Test cUSDC logo
|
|
curl -I https://explorer.d-bis.org/images/tokens/0xf22258f57794CC8E06237084b353Ab30fFfa640b.png
