API Providers
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
There are many services which offer a web API for accessing
|
|
|
|
|
the Ethereum Blockchain. These Providers allow connecting
|
|
|
|
|
to them, which simplifies development, since you do not need
|
|
|
|
|
to run your own instance or cluster of Ethereum nodes.
|
|
|
|
|
|
|
|
|
|
However, this reliance on third-party services can reduce
|
|
|
|
|
resiliance, security and increase the amount of required trust.
|
|
|
|
|
To mitigate these issues, it is recommended you use a
|
|
|
|
|
[Default Provider](..).
