Como posso entender por que uma transação falhou?

Astransações comfalha devem ser detectadase obter um código deerro retornadono Repregoply (RPC). Para queessatransação sejainjetada,indique umbug ou ummaumanuseio deerrosem uma carteira. Émuitofácil verpor queestatransaçãofalhou. Tentouenviar oequilíbriototale nãoterfundos suficientespara cobrir a queimadura.

Vocêpode usar o RPCpara obter osmetadados. Nesteexemplo,você verificaria os Ofashesnonível 296452 ​​. O OPHASH Estamosinteressados ​​em seu link original é ONUEBJVRBAXTN4IK8KFZC4A8XTKFKYAFXINE698SLM3MTNIMDUS

Todas asinformações sobre oblocopodem ser acessadasem

https://rpc.tezrpc.me/chains/main/blocks/296452

Parafacilitar,podemosfiltrar a operaçãoespecíficaem queestamosinteressados. As operações sãoindexadaspor 2 valores. Oprimeiro índice será sempre 3para as operaçõesfeitas apartir de uma carteira.

O segundo hash de operação (índice 1) Aqui é o queestamosinteressados,então vamosencontrar o seu Ofashna localização 3/1.

Finalmente,pedimos ao RPCparabloco 296452 ​​e a operaçãono local 3/1 .

Você verá que oprimeiro código deerro é proto.003-psddfki3.contract.cannot_pay_storage_fee

Failed transactions should be detected and get an error code returned in the preapply (RPC). So that this transaction even have been injected indicate a bug or bad error handling in a wallet. It is very easy to see why this transaction failed. It tried to send the full balance and wont have enough funds to cover the burn.

You can use the rpc to get the metadata. In this example you would check the ophashes on level 296452. The ophash we are interested in from your original link is onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs

The entire information regarding the block can be accessed at

https://rpc.tezrpc.me/chains/main/blocks/296452

To make it easier we can filter out the specific operation we are interested in. Operations are indexed by 2 values. The first index will always be 3 for operations done from a wallet.

https://rpc.tezrpc.me/chains/main/blocks/296452/operation_hashes/3

["ooeujV9F66p54xzKL3d8UgsdriAPwqroipLZRdVXVJKpD6oAMJA","onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs"]

The second operation hash (index 1) here is the one we are interested in, so we'll find your ophash at location 3/1.

https://rpc.tezrpc.me/chains/main/blocks/296452/operation_hashes/3/1

"onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs"

Finally we ask the rpc for block 296452 and the operation at location 3/1.

You will see that the first error code is proto.003-PsddFKi3.contract.cannot_pay_storage_fee
